my car runs like **** when ever i turn on the ac when i turn off the ac its ok and it seems to only run bad at a stop! its starting to p!ss me off also feels like im loosing power!

 

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?
