I'm surprised it didn't set a code. It sounds like a bad coil pack or the boot on the coil pack that attaches to the plug could be arcing. If the light still hasn't come on, check fuel pump pressure. Also, if the light has come on and then has gone off, check for codes. Many times the light will come on when there is a misfire and when it stops, the light goes off.
