    Headers

    I just installed a new pair of pacesetter headers and left the stock cat back now my car runs like crap. During acceleration my car bogs bown and back fires. I also experienced an extreme loss in power especially at take off.
    Any ideas of what could be causing my car to run so shitty.

    What codes are you throwing? Did you use 02 extensions or attempt to splice the old ones? Any exhaust leaks? Loose plug wires? Chipped plugs?

    gotta be something with your O2 sensors, b/c i still have my stock catback on mine with kooks headers and no problems, you also may just be running horribly rich, that would cause your symptoms...

    O2 sensors are toasted.

    Should have bought the O2 extensions and not spliced them.

    Exactly. When you're dealing with millivolts, splicing doesn't work so well.

    agreed.....get some pre-made extensions and that should fix you up. Also, make sure you don't have the fronts plugged into the rears. The front connectors drop down off the k-member.

    Also the coating on headers has been known to contaminate O2s during the initial heat up.

    if the o2 sensors are out would the check engine light come on and would the catalytic converter have anything to do with the backfiring

    it definitely sounds like an o2 issue but I would almost bet you it's those home made extensions. I've seen it a bunch of times. People use those and have issues.
