Check Engin Light On

Hey,
Just installed a turbo back exhaust system, extra long downpipe that eliminates the cat and then a catback apexi n1, on my 95 eclipse GST. After i drove for about thirty miles and my check engine light came. Imediately I thought that one of my sensor was tripping the light. My questions are...first, is this a correct assumption? second, how do i get the light to turn off so i dont have to ride around with it on. Is there any way to remove the sensor...does that work? Has this happened to anyone out there. Dont know what to do, please help. Thanks.

Probally a CEL for the cat. You can do a resistor mod for it. Otherwise it won't go away.

well once you think you have it fixed unhook the battery for a few min that is how i got mine off...but if it isn't fixed then it will come back on

Ya u can just take it to autozone too they will check it for free.

2003 s10 engine light staying on.Had GM dealer check ,code indicated PO1071 fueL trim lean.System test showed that fuel pressure was low,I needed a fuel pump.I put on the pump & drove 75 miles & the light came back on...any Ideals???

Please post in the correct forums, your in the Eclipse, Talon, Laser area and you also resurrected an old thread so please go to the right area before posting again.

It may happen in any model or make car. First remove your gas cap and reinstalled it to drop the vacuum pressure and to check engine light will come on all the time. If you are handy, go out and disconnect the POS. Post of THR battery. Leave it off for 15 to 20 minutes. This will erase all failure codes and reconnect the terminal. No light, no more problem
