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

Re: O2 Simms
Don't waste your money on the sims ...for the same price you can have your car tuned and program them out ...

Re: O2 Simms
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.
