Oxygen Sensor=Check Engine Light???
Don't know what's going on but just gota reading from my sct tuner of an oxygen sensor either going bad or something may just be messed up electrically but I was wondering if anyone else has experienced the same thing or something close to it...my mods are dyno tuned and longtube headers w/ o/r xpipe and sct tuner and jlt intake....I was just underneath the car earlier this week and everything was fine...I wish I could remember the code that I got but I'll get it tommorow...

RE: Oxygen Sensor=Check Engine Light???
What code are you throwing? After I installed my longtubes and o/r x, I kept getting like a P0443 code. I called Brent and Dave at Brenspeed and they looked at it, but could only determine it had something to do with some emissions. They modified the tune to turn that specific code off and it hasn't shown up since. Afterwards, maybe a week later, I got another CEL while driving around. Scanned it and it was P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1). I reset the ECU and it hasn't come back since.

P0133 02 sensor circuit slow response code is a common code when having longtube headers. Bank1 sensor1 is the passenger side front 02 sensor. Remember when using longtube headers your front 02 sensors are further downstream, which takes them a little longer to heat up and start responding properly. It doesn't mean the o2 sensors are bad, they just need to warm up a little longer. So when you start your car up don't just put it in gear and take right off, let the rpm's come down slowly on there own. You may still get the code from time to time but this should help some.

I just have one question. I am about to install an O/R H-Pipe from Jegs tomm. Is there anything I should expect to happen after I install it? Will the CEL come up and if it does, How do I get rid of it?

That's the same exact code I got so it is safe to just reset the ECU and delete the error w/ the tuner....thanks for the responses!!
Resetting the computer will not eliminate the problem, only the code. Is it safe to clear codes? In most cases, yes. Is it safe to assume that just because the code is not present, a problem isn't there? Absolutely not. Your response was like: You survived a plane crash? Awesome, that means I will be okay if my plane crashes! Thanks!
That's very similar to paying a doctor to say "you don't have cancer" and then believing you don't.
I hate to sound so critical but I feel bad not saying anything and just letting you believe whatever you may.

The CEL will definately come on without cats. Emulatorswon't work well as the PCM makes sure the cat can be rendered inefficient on command from time to time. A new calibration would be the most ideal way to keep the light off with off road pipes.
