I just gutted the cats on my 99 Camaro SS and it turned on the SES light, so I installed o2 sims and the SES light did go off. So I reset the computer and still did not make a difference. I put the sims on behind the cats.
Any help would help.
thanks

What meathod did you use to reset the PCM? Do you have a scanner to find out what DTC exactly is causing your SES light? Maybe you have a bad O2 sim(s)?
