02 chevyHD 4wdwhat does it mean if oil presure goes up while driving?
It is suppose to go up. As engine RPM increases, so does the amount of "preasure" or flow of oil . Each engine/manufacturer has "limits" on the amount of preasure that any given engine can tolerate. If oil preasure "exceeds" these limits, it can lead to faliures within your engine....ie: blown gaskets, seals etc. If you are using a "thicker" viscosisty oil, this will also increase your oil preasure, especially during "colder" weather. Check with a dealer, they should be able to tell you what your perimiters should be for your oil preasure....low/high readings.

Answer . nothing it is normal oil psi. go"s up & down with RPM . the pressure relief valve is probably stuck have it checked or you could blow all the seals
Answer . Considering the speedometer shows speed and the car doesnt move, it sounds like a broken drive shaft. Seems odd since those normally go bad on the road, but the …reason I say this is the speedometer sensors on 99% of cars are afixed to the final drive of the transmission, right where the axles go in. the tranny is not at fault if the car registers a speed. It has to be somwhere between the output of the tranny and the wheels. Good Luck
Oil Light comes on during idling and while stopped at traffic signal goes off when I give it gas and while driving. Checked oil and it is full.?
The Idiot light could be bad or you could have a slug build up issue. Perhaps a flush is in order. I have heard good things about Auto RX. Hope This Helps.
The oil pressure light flickers on for a few seconds while steady driving on my 1995 Taurus 3.0 liter is it a pump or oil presure sensor?
Flickering oil light... . Back in the old days, cars used an oil pressure gauge - and then along came what are sometimes referred to as "idiot lights" that took their place…. . The very same function is being performed: letting the driver know if the oil pressure, therefore the oil levels are getting low. . The flickering light lets you know the oil level is right at the point of being able to trigger the light on the dash. . Also, when the engine is just idling, the pressure is lower and light goes on. When the car is moving though, the engine is turning over faster and the pressure builds up and the light goes off. . NOTE: if your oil pressure light comes on at all, the engine is at least 2 quarts low! . The #1 cause of engine failure is engine oil neglect - running oil too long between changes (if any at all!), and running with not enough oil. . How do you check the oil levels? . The Owners Manual will have all the details and even illustrations on how to take care of your car's oil. . Answer . \nLow oil level. Add oil.. Answer . \nOil pump defective, oil sending unit defective, low oil, bad guage. Answer . 1. Defective switch\n2. Short in wiring\n3. Worn oil pump\n4. Worn bearings\nHook a direct reading guage to the place where the switch screws in to see what the actual pressure is.\nIf the pressure is good, look for electrical trouble..
Backing up while driving is putting your car in reverse with yourfoot on the brake and slowly letting your foot off the brake. Ifyou are pulling out of a parking spot you migh…t turn the wheel.
Most likely cause is a failed sending unit in the tank.
1999 dodge 1500 van and the oil presure gauge drops to zero when im driving and goes back up and after you change oil it does not reoccur for months?
Hopefully (for you) just a bad oil pressure sending unit. Install a manual gauge to actually check the vehicle's oil pressure
Worn main, rod and cam bearings, worn oil pump and clogged oil pump pick up screen, all contributed to high mileage, lack of maintenance and abuse.
1989 Chevy S-10 in cold weather shows is good oil pressure while driving but when the motor idles the pressure goes down and chech gauge lights up?
Your oil pump is probably finished. If you have recently changed the oil, it's definitely finished. Oil becomes less viscous when it heats up and your oil pressure drops becau…se the pump can no longer regulate the pressure.
Why does 4-cylinder 1998 TJ with nu oil pump and sending unit when warmed up while driving then at idle or stopped at traffic lite oil gage goes to zero and chk gage lite comes on?
If the oil pressure is up when the engine is cold but drops once the engine warms up a bit, you probably have worn rod and/or main bearings. The oil pressure created by the …oil pump forces the bearing to stay away from the crankshaft. But over time the bearing can wear a little, especially if a poor quality oil was used or if the oil was not changed regularly. Once the space between the bearing and the crankshaft expands from wear, the pressurized oil leaks out faster and the oil pump can't "keep up", resulting in lower oil pressure, even though the oil pump is moving just as much oil as it ever did. Sometimes you can temporarily solve the problem by changing to a heavier grade oil. For example, if you've been using a 5W15, change to a 10W30 or even a 15W40. BTW, you probably didn't need the new oil pump OR sending unit.
When shifting your 2002 Bravada into reverse the vehicle revs up but does not move It goes forward though while in drive why is this?
You probably have a broken Sun Gear from hammering into reverse. Its a cage thing that only works the reverse gear. It holds a set of clutch's. You have to pull the entire tra…nsmission to fix. Its almost the last thing before the output shaft. Around a $50 part.
If it drops to zero it is the stepper motor in the cluster. If it drops down several degrees then it is the thermostat and will eventually make the check engine light stay on.… you will experience poor fuel economy due to the computer loading the engine up with fuel thinking you are in warm-up mode.

my oil pressure goes up while I'm driving and back down when I stop what could cause that
In Auto Parts and Repairs
Your alternator will stop working, your motor will heat up and you will need to call AAA asap. What makes it even worse is that on significant number of cars the belt is also… driving the power steering, so it will suddenly become very hard to turn the wheel. On high way speeds it results in a very dangerous situation.
In Car Starting Problems
It can be many things. Bad fuel pump, clogged fuel filter, blown fuel pump fuse, bad fuel pump relay, and many other things. You have to determine what you are missing, fuel o…r spark. Then you will know if it is a fuel delivery problem or electrical problem.
In Car Stalling Problems
A car that turns over but won't start means, the car can have the anyone of the following problems. Not enough gas in car, battery has no full charge, the fuel pump is not tur…ning on, the engine is not getting gas to it, and the spark plugs are not firing.
In Chevy S-10
Not much info to go on but, if it is a GM product I would suspect a fuel delivery problem, either a fuel pump going bad or a plugged up fuel filter.
