I have an 02 Ecotec. My check engine light has come on for the second time now. First time it came on, car seemed to not want to shift from first gear(Auto). Had it scanned, no codes, pulled PCM fuse for a bit and once back in, no CEL and no problems. Tonight (about a week later) same deal, CEL on and car wont kick in to next gear. I plan to go get it scanned again, but figured i would pick a few brains here and see if anyone has experienced this issue before. Nothing new to the car besides an oil change and air filter. Checked the gas cap, its on tight. Also, if memory serves me, it has been raining both times this has happened though i doubt that matters LOL!
