Cool good to know...and ur question is?lol

I think he wants to know what to do or what the problem might be. I think it might have something to do with the IAC and/or the dashpot decay rate in the tune if the car's been tuned. Do these cars have idle sensors or anything like that? Could be maf related as well.

How many miles are on it? Clean your iac, maf and change your fuel filter and if you havent done so yet, do a tune up (plugs wires etc...).

lol sorry it was a question/rant, this started happening when ever i removed the cats :/ but I'm going to try the things you guys suggested!

its got 129899 on it!

Put mil's on it or get a tuner and turn the rear o2's off. rear o2's could be throwing it off.

where's a good place to find a cheap tuner thats good i need one anyways?

http://www.americanmuscle.com/sct-x3...ash-tuner.html Heres a link for the tuner. As for the o2 sensors all they do is check if you have cats they dont affect your a/f ratio. But if you havent done anything ive mentioned yet i would get on that lol.
