The headlights will turn on and off by themselves when the car is just sitting. Nobody will be in the car and it won't be running. It seems to happen at random times. This is very persistent and kills the battery almost daily.

N it was hard to turn my wheel is it my power steering pump n if so what parts will i need to fix it

The guy did a diagnosis and told .e he could not determine if its a blown gasket unless he takes the top of engine apart and charged me 500 to do so.. Did he cheat me??

I'll change the course pack the crank sensor the fuel filter in my car still wont start I took it to 3 people and each person said it's not getting a spark so can someone please tell me what else do I need to do is not the security we done check that so what else could it possibly be please help me?

Then it began to stall then kill. Now it doesn't want to start at all. I have changed spark plugs and wires, and battery. What can cause this problem?

The signal lights on the drivers side work intermittently comes up on dash display as "front signal out" or "rear signal out" thought the bulbs still work. When the message appears the blinker blinks faster. When the fog lamps are on the front signal will not work on drivers side. A couple of times during a drive the dash display will say service traction and service abs. If you shut off car it will go back to working. Sometimes it just says abs or just traction. If the heat is on full and you turn the wipers on the heat will stop working (replaced thermostat already). It looks like lots of random electrical problems to me but I'm not sure where to start looking. Please advise?

It don't do it every time but it happens alot.I mean you can push the gas petal all the way down and it will push out of it.but it a like after you take your foot off that's when it starts going

It happens when I try to accelerate quickly. If I go slowly, I don't notice it.

Changed today drove about five miles car cut off and won't start.

I have a Pontiac grand prix and typically when it's first started or after it has Sat for 30 mins or so on restart engine has rough idle, when given gas steadily it will still lose rpm in which you have to pump the gas again, sometimes it straightens out sometimes it dies and heads up display says reduced engine power and won't restart, where we then have to unhook the battery and wait 10-15 mins, hook back up then restart and give it gas until it straightens out. Mass air flow sensor has been changed.

Track control off light stays on and the RPM drops to zero. Car idles too fast. Key gets stuck in ignition. Can anyone help me?

My radiator fans are not turning on at all. Which is causing my car to run very hot and overheat. I've checked the relays and that's not the problem. I for one do not know how to troubleshoot this issue. I don't know whether I should just replace the temperature sensor or the fan motors themselves.

problem started with no cranking once in awhile then started back firing and it cranks but wont start. sometimes it wont even crank.other times starts and runs fine for a while.shows no codes when running.

Downstream ak at map sensor, melted MAP sensor ground wire, fans then shut down,replaced thermostat,plugs melted off.replace the plugs. At 30Mph it was dead in the water. Got it home & pulled codes 141, 171, 300. Replaced Downstream o2 sensor,battery, engine thermal sensor (under thermostat housing). Achieved idiocracy by erasing codes and evading loop mode. Coil check acceptable , correct resistance at plug wire connection on top, continuity though no resistance on bottom of coils. No trigger signal present at ignition module w/ homemade LED tester and engine cranking over.Temp light on Comm..Makes plugged, then flooded sound when attempting to start. Found pcm in 2000 bonneville that I can have reprogrammed for $100, but have recently spent $300 + $7,000 in suspension,steering components, cabin components instruments and tires and wheels, prof. body work+ have much love into it. Is there a temp sensor capable of causing shutdown or no start, or could it be a knock sensor

Ticking type noise in the motor at high acceleration

Water is not mixing with oil.

Phones won't charge anymore. What fuse is it listed under in vehicles fuse box?

It's shaking dragging and when I stopped at a light it cut off. It is now loud and has a foul smell

I read the article on this site:


I understand from this article this can be considered serious. The yellow ABS light has been on for years and for a long time the red brake light would come on intermittently. I could be parked in a parking lot with the engine running and light might just come on or go off. It does not flash or come and go quickly. It was off for months. Then back on again.

Brake fluid has never been low. Sometimes the light would come on or go off if I hit a bump in the road just right. I'm not kidding.

Now the red light stays on and therfore won't pass inspection. A diagnostic was done at the issue was determined to be the ECBM module. Unfortunately, this part is not made anymore and apparently the 1997 used a different kind of ECBM than the several years worth of models before and after it.

Garage working on it has gotten 2 different 1997 ECBM modules and neither has solved the problem and now they are doing "further diagnosis". This is racking up a major repair bill for a car that I don't drive more than a 1000 miles a year. I'm getting frustrated and just looking for some sense in what could be going on here as the mechanics seem to be stumped right now.

Thanks in advance for any info anyone can provide.
