    Are your headers hitting your swaybar?

    You need a tune. One done with tuner hooked up to your car not one you can buy from a vendor placed on a pcm.

    I'll look into the DP issue and defiantly get a "real" tune. Thanks guys!

    Edit:
    Being an 04 compg will I have any issues with the sway bar? IIRC the sway bars are different.

    Thanks

    Even if they are different from the 97-03...all your doing is flipping it...so no.

    What is the definition of flipping it. I looked it over Friday when i did the front brakes and didn't quite get it cause i didn't understand what to do or couldn't remember.

    take your swaybar, unbolt it, flip it upside down, re-attach it.

    btw I looked at the sway bar and it's pretty far from the headers. I did notice that the front o2 sensor was tight up against the firewall, could that be the issue? My cars got 83k on it so i'd like to replace it soon anyways. Do they make shorter o2 sensors?

    sweet. a bfh is my favorite tool

    83k isn't old but isn't 100k the recommended time to replace it? Also getting a crappy 15 mpg right now which is another reason to replace it.

    what are you talking about replacing?

    and 15 MPG means either something is seriously wrong or you're in the gas way too much.

    edit: oh the O2 sensor, it should be good for quite a while. Apparently they're over-replaced.
