Yes on that motorized
throttle body you will need to reprogram it. It needs to be re-calibrated. You may need a new gasket.
First, UN-PLUG the harness and remove the T/B Carefully clean it with T/B cleaner and a tooth brush. It can then be reinstalled.
DO NOT get you finger in there with the harness connected. The motor will cut it clean off!
The computer needs to Know the closed idle values. It can also affect shift points in the transmission.
To Re-calibrate. Disconnect the Neg Battery Cable. Cover the Ned Battery post with a rag.
Using a jumper wire connect the Pos Battery Post to the Negitive Cable ....for about a minute or so, this will drain the capacitors. This will drain/ erase the memory from the
PCM.
Now you can re connect the battery.
All accessories must be off.
Turn the key to the on Position. let the cluster Prove out and all lights come on. this gives the T/B time to Fully Sweep to wide open and back to idle.
Start the car Let it run and warm up 15 min as it learns the cold to full hot values.
It will learn the throttle angle and the desired RPM.
This can be monitored with you scan tool if you have one .
Let the car run for another 10 minuets as it learns the proper idle trim .....
Now take it for a test run ........ It will relearn as you drive....
