Every since I have gutted out my cat and put on my new exhaust, (which has been almost a year now), my check engine light keeps on trippin even if i reset it. What would cause it? I have no clue. I have tried to turn the key off on off on off on trick but it doesnt work. I got tired of looking at it so i took the bulb out. Maybe you guys can help me out on this.

dependin on the year of your clipse will tell ya if u can do the key dance or not. i cant on my 99 there is a link on the main 2gnt.com page that has the PCM code/key dance writeup
your CEL is probably on cuz there is no voltage cummin from the rear 02 sensor. some people get a CEL, some dont.
there is some type of mod u can do to fool the ecu.
maybe something else is wrong??hope not, but u shud look into it if your CEL doesnt go away after resetting the ECU.
also, leave the neg connection off the terminal for at least 15 minutes.
