My engine idles rough all of the time. It also doesn't have any power util about 2200 rpm. I tried cleaning the throttle body, but that didn't seem to help any. When I disconnect the small vacume line from the bottom of the tb, it idles fine, but at a higher rpm. Any suggustions?

There could be many reasons for that.

Have you swapped back in the stock chip? Is it still the same.

What have you done to the car recently?

 

The most recent things I have done is gutted the airbox and remove the maf screens, but ir ran fine after that. It started doing this about two months ago and gradually got worse.

well I think that little vaccume line under ur throttle body is for ur cruise control so.

 

It comes from the fuel vapor canister, and goes back to the egr. Will it matter if I just disconnect it from the tb?

Could this be a problem with the fuel vapor canister?

Could the egr solenoid have any thing to do with this?
