Might be sensor problems. If the cars runnin too rich, or not burning all the mix, it goes down the cat and sticks there. Also, according to OBDII codes, if O2 sensor near the cat doesn't get the proper range, it'll start freakin out. Changing the flow of the cat (i.e., NO cat) means the temp won't be quite right, at least not what the ECUs expecting. Might set off the MIL light. Probly' no big deal, but wouldn't be surprised. <br>

I have an 03 sunfire and I want to eliminate the cat. I have tried to get an answer on this in the jbo site and nobody can answer me about it. please let me know if anything goes wrong with the cat out. I'll bet that the car sounds good now!
Thanks

Cheesecake if you find an o2 sim please let me know! I can tell you that casper electronics does not have anything and rk sport advertised it however when I contacted them they told me it would not work with the ecotec. Hope you find something.

t is a inline splice into your stock o2 sensor wiring. Also requiers you to have your o2 sensor installed in the exhaust..
And works great with a high flow or NO cat at all.

IF YOU USE A 02 ELIMINATOR WHY WOULD YOU HAVE TO HAVE A SENSOR IN THE EXHAUST AND NOT JUST STRAIGHT PIPE OR PLUG THE HOLE?

ok i know cheescake said the rk sport 02 sim wouldn't work but i had already ordered it and wasn't about to waste my time sending it back........so i put it on the car. i have to drive about 120 miles this evening so that should be a good test for. i will let you know what happens this evening.

LT1XLR8 i haven't heard back from that don guy. i told him i wanted the sim and asked what i needed to do to get it but he never e-mail me back. guess i will try again. anyhow i didn't make it 30 miles and the light came back on...so it's back to the drawing board.
