02 trailblazer engine goes to idle when running 65 mph or more this has only happened when pulling a trailer it will run fine when you pull over and let it sit for a second or so then it will do it ag?
It's probably fuel starved. check the fuel filter. i am having the same problem only now it happend when i was not towing. i changed my fuel filter and it still did it. i think it may be a fuel pump going bad. i did take it to a shop but they had no clue what they were doing and told me that my truck was fine. i told them to test the pump with a guage but i don't think they did it right.please let me know what you find. thanks. firstname.lastname@example.org

Your throttle body is probably dirty,The throttle body has a hose from the air filter housing attached to it,the throttle body is attached to the intake phlenum.Take the hose …off(its rubber with a clamp on it).Do this with a cold engine, NOT RUNNING ! spray some carburetor cleaner inside the venturi and scrub it with a toothbrush,on the side of the throttle body there is a place where a cable goes into,twist the direction of cable to open the throttle plate(inside the throttle body),and continue to clean.Now put it all back together.What happens over a period of time is the Throttle body gets clogged with carbon and cannot breath at idle, the throttle plate when close(at idle)has a very small air gap and cant breath when dirty.If this does not cure your problem,then you will need to consider having your ais motor check.ais= automatic idle speed motor.For this you will have to take the throttle body off to replace it and the screws have been installed with locktight and are tricky to get out. ,I did not know what year or make of car, but its a common problem since the fuel injectors took the place of the carburetors. . Be careful that any cleaners used are for Fuel Injected systems and are O2 sensor safe. Some Carburator Cleaners can damage FI components.** . Spraying a throttle body spray cleaner, such as one sold by STP, to clean the throttle body, then starting up and revving the engine, may be enough to dislodge the carbon deposits and material blocking the airway. The original poster's solution is the cheap and easy way to handle this problem of low engine RPM causing stalls. Try it first, it is a fast fix, and it worked for me, causing my engine RPM to go up above the stalling level when my car was idling at a stop sign or red light. I had this problem just two days ago. When the rpm goes below 1000 it stalls; visible black smoke is also observed at the exhaust when it's rev up. Try changing the air filter as this might be clogged up causing an inefficient air/fuel ratio. When there's not enough air going into the system complete combustion is not achieve causing this problem. Good luck. Pls let me know if it solve your problem. Answer I had a similar problem. My 97 Jeep Grand Cherokee would run fine whenever I would accelerate, but once I took my foot off the gas, the RPMs would drop to zero and stall. Sometimes it would drop to zero than catch idle out low, but stall again later. I got a $300 tune up that did nothing. The problem turned out to be my IAC motor, or the Idle Air Control Valve which sold for $80 at the dealership ($30 at Autozone). If your car is doing this, replace this part! It would also stall whenever I took a turn slowly or tried to pull into a parking spot. ! Thanks to this forum, I diagnosed this as my problem, and I want to share with everyone else who may be experiencing this frustrating problem. . (addition by LucheLibre) My 87 Jeep Wrangler had the same problem. Did some research and found that older jeeps use very thin idle tubes mounted in the venturi. These can easily become clogged and fuel will back up and come out the main nozzles, causing the Jeep to run too rich and die. The solution is quite simple. Pull the air cleaner housing and choke plate off--remember to keep an eye on how the choke linkages are connected to the carb--unscrew the venturi and pull it out. You can't miss the tubes. Run a long, very thin wire or pin down the tubes and then reinstall everything in the reverse order. Your Jeep will literally be good as new. If the same problem comes up again, then your float bowl is junky and clogging the tubes again. Clean the bowl and change your fuel filter. Answer I have a 1996 sunfire 2.2 litre engine that is doing the same thing, i have replaced fuel pump, plugs, wires, fule filter, air filter etc. Answer The fuel injectors get dirty and clogged. I add some fuel injector / carburetor cleaner to the gas tank and it usually clears the stalling at idle problem. Answer I am experiencing the same problem with my 96 eclipse RS. I replaced the air filter- that didnt help, i added fuel cleaner- that did nothing- I have a fule filter but i don't want to waste the money if that's not the problem id rather return it and get my money back! So let me know what works for you guys experiencing the same problem! Thanks a million! Answer My 1999 PONTIAC Montana would stall intermittently when I would remove my foot from the accelerator and slow down. Dealer replaced the IAC motor and cleaned out the throttle body but the problem persisted. I disconnected the connector to the throttle motor and the air intake dampers and bent the contacts to improve contact mating. Frequency of stalling was greatyly reduced. Next I will clean the contacts to remove oxidation.GM uses cheap tin plated contacts. Answer i had the same problem as the 96 eclipse, but with me 91 Mazda... the main problem was the air hose so we duck taped it up until we buy a replacement. a little bt later the whole engine went bad and the head was warped and had a few cracks. Had that fixed and it ran great, then we started seeing whitish blue smoke from the exhaust... we're going to replace a vacuum modulator and a seal that a friend just added to the car after breaking the new one. We had also replaced several things first and tried the fuel cleaner. Nothing seemed to work or it would run okay for a mile then start up with its bad again. Good luck. Answer Idle control valve is not working. If it is a fuel injection system, check the fuel pressure controller also as these go hand in hand. Answer The "automatic idle speed motor" may also be known as the "Throttle Position Sensor," but it could also be the "Idle Intake Valve." The latter would be the one I would look at, since it's the one that's taking in air while the car is idling, i.e---sitting still with the motor running. If it's clogged, your car will die when it's not requesting power from the engine to accelerate. Answer: I've never known an "automatic idle speed motor" to be considered a throttle position sensor. An "idle speed motor" is just another name for an "idle air control valve" or "IAC". I've seen this concern many times. Most of the time it was caused by gunk becoming lodged inside the IAC passage. That's one of the easiest things to inspect at least. Answer Have you checked all the corroborator vacuum hoses. That sounds incredibly the same as the problem I experienced with a Honda I owned once, the solution a mechanic showed me was to use a pair of needle nose pliers and slightly clamp on each hose at both ends ( without clamping hard enough to break the hose ) until the engine would idle normally. That said once the problem vacuum hose is located you would merely replace the hose, about a .99$ fix at autozone. Take the hose in with you to compare. Tell them what its for and the specifics to make sure the hose will last. Another possibility, a stuck open or sticking EGR valve would also cause those symptoms.
%REPLIES%. Answer . If your issurance has run out and you are pulled over what happens can depend on your driving history. If your driving record is good the worse that ma…y happen is you will be ticketed for $538.00. If your record shows something your car may be impounded and/or your license suspended. on top of the ticket. You may fight this if you are caught without your proof of insurance with you, by going to court and bringing proof that you wer insured during the time you were pulled over.. Answer . That depends on where you live. In Anchorage, AK you get a ticket(somewhere around $150 for the Police) your car towed(towing fees and $13 a day storage to the towing company). Then you pay the city $250 to get your car back. After that you go to criminal court, and if this is your first offence they charge you $250 again..
Your car was running hot and it overheated you pulled it over and got towed to the garage What are the chances your engine is blown only could smell antifreeze?
Answer . If you stopped as soon as it overheated, you probably have no damage, unless the head gasket has blown. This would require replacing the head gasket and possibly r…esurfacing or replacing the head. Depends on why the gasket blew, if it indeed is blown. You may have nothing more than a stuck thermostat, bad water pump, low coolant level, clogged radiator, or a non functioning fan.\n. \n29s here, a mechanic once told me that the 2.5 motor could go through hell was gasoline panties on. just dont over fill or deprive it of oil.
98 dodge neon rt will out of the blue start to run roughly and will not idle if you take the car out on the freeway and get it up to 65 mph the problem goes away after a few weeks it happens again?
Answer . \nHave you tried a tune up with at least spark plugs and wires
What will happen if you don't show up for court in California for a speeding ticket Also the speedometer only goes up to 80 mph you were pulled over for 90 mph 75 mpg zone how will this affect trail?
Answer . \nShow up. It gets nasty if you don't. Criminal, actually.\n. \nThe speedometer may be addressed, but could also be thought of as negligence on your part.
99 Seville SLS - Any solutions when experiencing a rough idle run when starting cold that goes away after a minute or so and only happens when cold?
It could be a bad head gasket. Coolant gets in the combustion chambers and makes it hard to light the mixture. Check for exhaust smells in the coolant reservoir or gurgling …in there. If you have either or white smoke out the tail pipe, you've probably got a bad gasket. The oil will not get contaminated with coolant. Don't be fooled. Repairs are very expensive.
Briggs and stratton engine over idles runs so fast that oil spits out can only be shut off by pulling spark plug wire?
The governor is stuck, causing the engine to over-speed and not return to regular idle speed. You can check the travel of the governor by moving it back and forth with your fi…nger - there is not much travel, but there should be some. Check for debris or accumulated gunk at the lever where it joins the engine and clean it well. Ensure that the engine oil is clean and at normal level. A stuck governor will make the engine over-speed so fast that it can cause the piston rod to break. Good luck.
When stoped at idle shakes the vehicle unless in neutral engine idles like it has a ratackle cam if you rev it up over a thousand rpms it goes away and vehicle runs fine. I think it has a vacuum leak?
I would suspect you are correct. Replace all vacuum hoses under the hood if the vehicle is over 10 years old. Otherwise find the leak and repair it.
I have a 98 dodge caravan 4 cylinder my wife went somewhere the van was running fine when she was leaving the van had lost power it wouldn't go over 30 mph and wouldn't pull a hill at all?
It's possibly a plugged catalytic converter. The will shut an engine down as the engine warms the exhaust system throughly by stopping the exhaust flow.. If that's not the ca…se, I would suspect a fuel problem. IE: plugged fuel filter, dirty injectors, etc.
A 1994 Jeep Grand Cherokee Laredo drives fine then starts to bog down. If you pull over and start again after 3-5 minutes it runs fine again. What could be happening?
Several things could be causing the 1994 Cherokee to have thisproblem. There could be a drop in fuel pressure. There could alsobe a problem with the ignition circuit like a co…il pack breakingdown as it gets hot. Check these areas to start with.
I cut off the car the ck engine light goes off a doesn't come back til I go over 65 mph It run fine I had it check they didn't find anything but the check engine light still come on it doesnt stay on?
The check engine light turns on to inform the driver that the computer has detected a 'fault' and that the driver should address the problem. If the light is on constantly, it…'s considered a "minor" fault but something that needs attention as soon as you get a chance. If the light is flashing it means that something serious has been detected and you need to deal with it NOW! Unfortunately there is a whole class of "faults" that clear themselves and don't show up until next time the problem is detected... and it may not be until you go 65mph. You may need to connect the diagnostic code reader to the vehicle then go for a drive. You should be able to have someone with you so that one of you can drive while the other is operating the code scanner. That kind of problem seems like a pain but usually they aren't too bad once you have the code scanner helping you. It can also be a problem with OTHER systems, such as the anti-lock brakes. If that's the case you'll need to take the vehicle to a dealer or a brake specialist.
Your permit would be revoked and parents would be in serious trouble
In Chevy Blazer
I have a 95 Chevy blazer vortec 4.3 I am having problems with service engine light coming on and motor starts lopeing while sitting in idle. turn it off and light goes off runs fine some say oxigen?
More then likely the MAF (mass airflow sensor) is failing. have the local auto parts store scan your vehicle and it should be the problem.
i assume you mean .02 and if you 21 nothing will happen the leagal amount in most states is .08

Sounds like exhaust leak.
In Check Engine Light
What causes a 1995 cirrus to run fine 1 minute then engine light comes on car gets sluggish till you pull over restart car then light goes out till next time?
The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something t…hat is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
In Chevy Suburban
Why does my 2000 Chevy Tahoe with 5.3 engine show its overheating only when you pull a trailer an usually when you get over 55mph?
Sounds like a stopped up radiator. Do this to check it. Drive it about 4 to 5 miles and then bring it back home and turn it off. Open the hood and take your hand and reach ins…ide of the fan shroud and lay your hand on the radiator at the top and slide your hand down the radiator to the bottom. If the radiator feels COLD at the top or the bottom then replace the radiator. But first I would replace the thermostat and gasket. I changed the thermostat. It does not overheat unless pulling a trailer. I put a new transmission cooler on and that didnt help either. Like I said, Did you check the radiator with your hand ? You may also have a radiator HOSE that might be sucking closed when under a load. Check hoses and make sure there not TO soft.
