Question = I was driving in traffic today and my check engine light came on. My car kicks back quite a bit but not all of the time. There were no symptoms leading up to this and the car has not acted up since the check engine light has come on. Is it a problem that I can fix? Is it only a computer issue? It may be time for the timing belt to be changed?
MW: Answer: Todays GM vehicles use many sensor, switches, solenoids, and other electrical components to control or monitor every aspect of the engine. From controlling the fuel and ignition systems, to monitoring the emissions. A problem in any of these systems, or subsystems, can cause the check engine light to come on.
The first step in any diagnosis of the check engine light is to get the computer (PCM or ECM) scanned for codes. Any time this warning comes on, a code is stored in the computer memory along with many data parameters that were present at the time of the fault.
By what you describe, i would have to guess the engine is misfiring. Possible spark plug, wire, injector problem. If the above mileage is correct, this would be under warranty. So take to any GM dealer for a scan.
2009 Pontiac G6. We replaced head light bulb. Question: My driver side low beam headlight bulb went out so i replaced it, since then when my lights are on auto and i put the car in park, the lights go off, this never used to happen? Do i have a short or is this a fuse??
Answer: That problem does not sound like a fuse, but i would check them all to be sure.
Make sure you put the correct bulb in the headlight. A wrong power rating from a cheap parts store bulb can cause problems with the automatic lights. Make sure you did not disconnect any other bulb connector in the fender.
Check that the black light sensor on the front center of the dash is not covered.
If this all looks OK, you may have a DRL problem. They come on when the car is put in gear and sometimes are confused with the regular headlight.
