It was fine then outta nowhere it just wouldn't turn when i went to start.

Cold Engine surges at 1000- 2000 rpm and has rough idle till about 20 min., then it idles and runs normal. I unplugged the MAF sensor and the engine smoothed out and ran normal. Replaced MAF sensor with remanufactured MAF sensor ( not A/C Delco ) and the engine runs perfect. However, if I stop the car a few minutes and restart the warm engine, it surges badly, then stalls.Pretty much undriveable.

My heat and air barely work. The only time they do work is when I'm going more then 40 mph, and then they still don't blow enough to heat the whole car.

I passed everything on my emissions but my NOx was real high

Problem now for along period. Note battery will drain
if I leave it connected. don't know where to look for a short, or open. No codes read.

I have replaced the fuel filter,crank shaft sensor,coil pk, the cycl and/key. And the car will not start. it cranks but that's it. And the security light is on!!!! Please help this Greek Lady out!!!!

transmission making a whinning sound

Rear end rides low and scrapes over bumps and driveways. New shocks but airbags not filling up. The compressor works. Tried with 300 lbs in trunk still nothing adjusted level control sensor and still low. Now what? How do I test the sensor to see if it is good?

once I slow down to make a turn, whats the problem

Does it idling driving slow in town on the freeway. Then occasionally when parking it tries to take off like I punched the gas. I've been told oxygen sensor does this sound right

will not crank most of the time...all dash lights work battery has good connection, new starter and solenoid.no theft security light on or flashing bad ignitions switch?

Im pretty sure I have a bad cv joint the car clicks when I first take off stop or turn corners

ir will take gas then it won't over and over again until I let it rest and then it's fine again. Could this b a cooling sensor or the fuel pump?? Please help

It runs just fine until u drive it for about an hr than with gas pedal pushed down it will take gas than it won't. Could this b the fuel pump

My 1992 Bonneville SE is stalling after 10 minutes or less then won't restart for about an hour. Initially it wouldn't put up a trouble code in the computer, but finally kept it running long enough to set up 2 codes. 31 and 41. The PNP switch has been bad ever since I owned the car, but the 41 code suggests the camshaft sensor circuit or cylinder select in the ECM. I am assuming it is the camshaft sensor since in the code reader manual, a 31 can also refer to the camshaft sensor circuit. By pulling the gear shift down to drive and increasing the RPMs, I got the car to keep running past the sputtering and it continued to run fine afterward until shut down and the check engine light appeared and revealed the codes. The engine would not restart until it had cooled down for about an hour. When it does this, I have checked and noted that there is no spark from any of the ignition coils until it has cooled. I have cooled the ignition coils with alcohol, but still they do not set off a spark until the engine itself has cooled. Any one else experience a problem similar to this and if so, what causes it. Engine runs great when running and has always been dependable until just 2 weeks ago when this problem surfaced.
