Ok so I have a 2000 Pontiac Grand Prix GT. A few months or so back, the service engine light came on while I was driving. The car didn't stutter or do anything funny, it ran perfectly fine. It did so the whole time the light was on. I had stopped driving it for a few days with not knowing and when i finally got in a drove it, less then a mile just around the street I live on it went out. It hadn't come back on, still ran fine then all of the sudden yesterday it happened again. I was driving and all of the sudden the service engine light came on yet again. Car didn't do anything funny and is still running perfectly fine.
Any ideas as to what would cause it to do this?
I know my AC compressor is going out but doubt it would cause it to come on.
