Okay, my check engine light came on today and I'm not too sure why. It was only on for a few minute, when I started my car back up it hasn't come on since.

The only things I can think of are:

I think my plugs and wires are shot, would this cause it?

Or, I've been running leaded race gas, so it could be my O2 sensor.....

What do you guys think?

i did and found that my engine check light was cuz of a knock sensor problem. just dont forget, do not start the car when you are checking the codes, unhook the jumper cable before starting!!! good luck
