Ok two weeks ago i got my header and catback put on my 96 gs. My cousin drove it down to his shop and put it on real quick for me. When he got back i noticed the check engine light was on (this has never been on beofre). He said something about he had to mess with the wiring fromt he o2 sensor behind the cat.. now i dont know why he had to mess with the wire but he had them all cut and put back together with electrical tape.. he said there were two white and he might have hooked them up backwards. Well I was just messing with it. Theres two white, one black, and one grey. I switched the whites around and the check engine light is still staying on. Could the sensor of gone bad during the install? Do I have to reset the check light somewere?

I read on vfaq something about the ecu waiting like 20-30 minutes into a drive to flag the o2 sensor if its down. would it take that long for it to realize its back up? thanx
