    yeah it's you o2 sensor in your downpipe....like they said, you need a mechanical fix....they have them on ebay or any auto parts store....I got mine on ebay but that's cause I'm an ebay slut:keke: ...when you upgraded you downpipe it usually sets off your sensor...surprised it took this long to happen...

    It should only cost you like $2-3 at any auto parts store... you just need to do little drilling! ;)

    When you buy the spark plug fouler from auto parts store, you need to drill it to make the hole bigger to fit the o2 sensor in there... It basically backs out the o2 sensor using the spark plug fouler as a spacer so it doesn't throw a CEL

    Gruppe-S has a CEL fix ($13 Shipped), I had one but just sold it to somebody because I got AP instead.
