I put the Accufab plenium and 75mm throttle body on my mustang (4.6l turbo). After I finished the install and started the car up I noticed the car would stay reved up to about 2k and wouldn't calm down. After inspecting for vacum leaks and any improper installation I concluded everything was correct. The sucky part, the car is still having the rev prob and I cant figure it out ideas anyone? imp:

Idle screw? Does the throttle blade have a hole drilled in it (most aftermarket ones do)? You could block that off and see if it helps. Did you check the TPS after installation?

Ill try the tps suggestion, already did the other things. thanks man.

The last one i saw that had that exact problem ended up being the throttle blade not closing completely due to the blade hanging up in the TB. Just an idea

While the car is running see if you can manually close the throttle body. Maybe the spring is weak allowing the blade to open slightly?
