My car was running perfectly fine. I changed my oil then my car started idling weird and shutting off. Once it warms up and I drive a few miles it seems fine but before its warm it will start and idle at 1000rpm for a few sex then idle up and down and stall. Or I drove but when I stopped at a sign before it was warm or slowed for a corner it would just drop to 0rpm and die.

My sons car has a stalling problem that has no pattern as to when it occurs. Can restart after a few minutes. He says that he noticed prior the it stalling the speedo and the tach spike and then drop to 0. Would you start with the crankshaft pos sensor or the mass air flow sensor?

We think we are having tranny issues, and noticed that the HUD scrambles up and down when it is shifting into overdrive.

Low oil light came on so I took my cat a had oil changed. Brought to my work and liw oil pressure light came on. Checked oil and it looked like there was 2 quarts to much. Took it back to where oil was changed and they said I had water in my oil. So they did another oil change and it did the same thing right whenI picked it up. Have not drove it since. What should I do or what can it be and can I put Blue Devil Gasket Sealant in my motor.

After sitting for five minutes or so the car restarts and runs fine until it shuts off again. Sometimes within a mile sometimes not again for several miles or sometimes it runs fine for the rest of the trip! No codes are set when this happens and it only happens when the outside temp is over 90. Parts replaced; coolent temp sensor, fuel pump, crank position sensor, Iginition control unit.

this is my first time having this problme. help me out trid wasteing money on gas

took the cv axle out to replace them notice the fittings are different not sure if they r suppose to be like that thanks

when cruising 50 mph or 60 if i give it some gas the rpm's go up and then slowly come back down before it starts to gain any mph is that transmission slipping or what

occasionally there is nothing when you turn the key. If I turn the fanbelt just a little, it will start. The crank position sensor was changed with original part about 6 months ago.

all of sudden wheel got very hard to turn,than wheel keeps turning around and around ?? checked steering fluid and was ok??

air comes out cold on drivers side comes out hot passenger side??

what is the function of the crank sensor ??

what can i do to help get this higher

car will shut off while on the road or when stop will not start? will start eventully.

I have taken to autozone and they ran scan. All the sensors are good. Condition comes and goes but starting to stay on more frequently. Notice power steering doesn't seem to be working when lights are on. Gas mileage gets worse also. Any help would be appreciated...

It smelled like wire burning and I was wondering what could cause it. It comes on but that is about it. I took it to Autozone but they weren't able to run the codes

when cranking my car it has a really bad miss. the code reads random/multiple cylinder misfire. I just replaced the plugs and wires. I also tested the coil packs to check the firing and all produced a big blue spark like they should. what is causing this to occur?
