Okay, so my car now finally showed a code after 4k of miles. Can anyone tell me how to resolve this so it doesn't come back? I reset the ECU with my Cipher system. So it has been reset.

long thread, the o2 sim didn't work, but later in the thread some of the forum vendors starting pitching in, not sure if they came up with a fix or not...

I also made a thread about this. You can find it under my threads.
Tony contacted me a few weeks ago and asked me if I needed some kind of special muffler packing to insert into my O2 bungs. But ever since I reset the CEL about 1,000 miles ago it hasn't come back on.
But I have the older version 2.36" inner diameter HFCs. I believe the new one's have a 2.5" inner diameter.

I don't know if I have the older 2.36 or the newer ones; but I installed mine January of 2008, so I'm guessing that's the older model? How do you tell? Either way, I've been trouble free for 14k miles now..

I hate to change directions but a quick question, my friend just got a Service Engine Light or whatever, but from what I've heard you can take the car to like AutoZone and they can read the code correct?

I was having to reset the ECU daily and the rasp with the exhaust I had at that time was painful. I also had one crack at the support bracket and had to get a replacment. After that I gave up.

i used straight brillo pads. i just rip them apart and shake most of the blue soap off. then i just stuff them and blow thru them till i can barley blow. but then you need to add a little extra in there not stuff just lightly in there and let the o2 sensor push it down.
walker im sorry it didn't work for ya. if anyone guys order you some gtm test pipes. im curious to what they did.
