High idle after plenum install
I just installed a plenum and tb for a friend and the car is idling higher than normal. I've heard that sometimes the bracket that holds the throttle cable is set to far over....is that the case?

What year is the car?

Check the TPS sensor ( on top of the T/B )

Sorry, it's a 2001 GT

I had to drill out my bracket to make it fit correctly after the Dragon plenum install, so that might be what you have to do.

Either you didnt seal the plenum properly or you missed a vacuum hose. If none of that works then try resetting the computer by disconnecting the negative terminal, let it sit for 15 minutes then go back and start.
