any idea what could cause this or what to look for? Car runs fine but check engine light has been on for a week. Today I was sitting in traffic and I switched lanes to get into the turn lane so I goosed it a little to get ahead of the traffic and the check engine light started to flash, but then it stopped. Car didnt seem to run bad but I take it it didnt like that for some reason. It was hot out, close to 100 but I dont know if that would have caused anything.
Steady SES = emissions code. Flashing = misfire condition. Check all of your vacuum fittings. I don't know if an EGR or AIR system malfunction can lead to a misfire, though.
