I have a 94 z28 auto with 107,000miles I have a cutout no cat and an air foil, I just cut the front off the air box and put a k&n filter in and the Ses light only comes on when im at a long light at intersection or just idilling for a while. It wont come on if im going but once its on it stays on till i turn off my car and i have reset the computer already and it will still come on. I dont have access to s acanner and autozones one was stolen

Thanks

Do you have access to a scanner? If not, go to Autozone and they can pull the codes for you. Once we have the code, we can diagnose it from there. Is the car running poorly or do you just get a light with no symptoms?

 

Autozone only pulls OBDII codes. Since a '94 is OBDI, you need to find someone who can pull the code. It's the only way to find out, otherwise we could guess until Juvember comes around again.
