    engine light

    Hi guy, I have a problem. I just purchased an exhaust set from anew digital and it sounds and runs great. One problem, the engine light came on. Now the car will not be able to pass imisions with this on and I don't want the light on to begin with. (1) why is the exhaust causing that and (2) how do I make it go away? thanks. Tim

    Do you have 100-cell cats?

    Re: engine light

    i think :

    he should have , cuz the stock cats are welded with the exhaust .

    the problem is the sensors .. try to check if the sensors are connected properly on the cats ... then disconnect the battery for 20 min to reset the engine failure light .

    Re: engine light

    Probably O2 sensors...may need to be replaced (if the above solution doesn't work).

    Re: engine light

    I disconnected the battery, no light yet. There are lousy cats on this system so that could be it. Once I reset the battery, will it keep the light off? Will I pass my immision inspection?

    Re: engine light

    Only way to really tell is to go get the codes read!

    Re: engine light

    Thanks guys. I will wait until I have to get the vehicle inspected before I worry about the light. Will it cause any damage driving it with the light on? It's not like I am going to drive it alot this winter in Massachusetts anyway. Merry Christmas.

    Re: engine light

    it would damage the common sense side of my brain to look at any check engine light for a nano second longer than necessary...much less in my p-car...imo

    here is what you do....
    first of all its the cats causing the light to go on... obviously u didnt have it on b4 the exhaust switch. I had the same problem...
    did u buy it used? if so that is ur problem.
    here is what u do. switch back to ur stock exhaust and drive around....
    the car has to go thru a cycle b4 the system Oks it... if ur state had OOBD11 testing it will show up as not ready on ur current set up.... even if u disconnect the battery and reconnect it... the car has to go thru Evap and 2 other tests... including 02 sensors... and that takes a while... I tried and even though my cel was OFf I still didnt pass becasue the car didnt go thru the 3 tests... and thats when ur ecu light goes on...
    good luck,
    markski
