check engine light
Have the codes scanned to determine what is setting it off. Since it is going on and off, I would suspect the O2 sensor is failing (or the tune on the car is causing a valid failure that needs to be addressed).
I got a Pontiac G6 2008.I was listen to the radio.got out the car,got back in and my radio wouldn't come on.I looked down and my check engine light was on.went to auto zone and they hook it up to see what was going on.and some codes popped up.each code got something to do with the heater control circuit sensor.But at the top of the report is say OXYGEN SENSOR (02S).PLEASE SOME HELP HERE.
