O2 Simms

Is the SES light set by no rear O2 sensors going to effect performance at all or is it just an emissions code?

I believe it's only to eliminate the "Service Engine Soon" light to come on.

Re: O2 Simms

the code triggered by the rear o2 sensors with the cats removed is STRICTLY a dumby light. has NO affect on performance

May have made stupid post* edit Was going to talk about flat a/f ratio at 12.9, but that would be the front 02 sensors that calibrate that. :D
