i have an 87 turbo II with a 91 turbo on it and the air pump is gone. i put a cover plate over where the valve was and now the ilde bounces from 700 to 1300 rpm. the tps is brand new. would anyone happen to know i can do to fix it?

 

Block off plate leaking a bit maybe. Weak guess. The cycling idle.....did it start after the new turbo or after the acv was removed???? One of those hose that went to the acv was a vacuum, the other two were more than less pressure. Is the one that was vacuum *switching solenoid*, not plugged???? The hose that is.

 

it started after the avc was removed
