I have an '02 sunfire (ecotec L61) and have made the following modifications:

lower engine mount
short ram intake
platinum +2s
synthetic oil

now I'm having a problem with my dash lights going on and off. While driving, I've had the cel go off, the theft light, running lights failed, brake light and air bag lights, everything was going on and off. my temp sensor shut off and then came back on, and i noticed that occasionally power was not going to the wheels. has anyone had a similar problem or experience with this kind of situation, and if so, is there any advice you can give me? I'm probably gonna have to take it in to the dealer (goodbye $$$ ) and have them look at it, but i'd still like your input. thanks
