If you dont have cats you might wanna get mil eliminators. Otherwise you can just unhook your battery for like 20 minutes and that will reset your computer.

The light will come back on there next cycle after you do that.

Invest in a nice set of MIL elminators or a handheld or custom tuned chip can shut them off.

It will be an ongoing issue if not corrected and can actually effect the performance of the car depending on what the PCM thinks the car is doing.

Well I'm just relaying to him what I've been told. Plus I have an o/r h pipe with mil eliminators and my SES light is still on. Whats up with that?

Is the SES light an O2 releated issue?

If so the MILs may have gone bad. They typically don't last nearly as long as the O2 sensors themselves. And the inline stuff is just junk.

Well lets see. I had the car for like 6 months and never ne SES light. Then I get the o/r h pipe on, but I didnt hook up the mil eliminator right away so the SES light came on. Then I hooked my BRAND NEW mil eliminators in yesterday and the light stayed on. So the SES light better be on from the new h pipe, but then again I didnt waste 50 bucks for nothing, so that damn SES light better go off.

Pull the plug on the battery for 20mins or wait out the light until the next check, which usually takes most people a week of driving to get.

Ok thanks. I'll wait about a week or so and if the light is still on I'll just unhook the battery.
