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? :pimp:

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?

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?
