2006 Pontiac G6 Engine Light
2006 Pontiac G6 Check engine light.
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 and runs bad. 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 if this engine even has one.
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. You may have code P0300 stored.
By what you describe I would have to guess the engine is misfiring. Possible a bad spark plug, ignition coil, plug wire or fuel injector problem. If the above mileage is correct this problem would be under factory emissions warranty. So take to any GM dealer for a computer scan and repair. Your car has a timing chain not a belt.

2009 Pontiac G6. We replaced a 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??
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 headlights. There is a common problem of a burned resistor for the DRL. It is inside the passenger side fender. It mounts with 2 bolts. It is a white ceramic block. When these go bad the daytime running lights do not work. It can be tested with a volt / ohm meter. You would need to check continuity. A bad resistor would show as an open circuit. If it is bad it would need to be replaced.
