Ok, first, the lever MUST rest on the stop screw. Otherwise the throttle position is never the same and the computer don't know what to do , so it idles high.
1. Warm up car
2. Turn engine off and REMOVE THE KEY
3. Disconnect negative lead from battery and turn head lights on( this removes the capacitive charge in the system)
4. Connect negative lead to battery
5. Back off the stop screw on the throttle body
6. Start car
7.While grasping the throttle lever with your hand, give it a small amount of throttle and let off SLOWLY.
8. Adjust the stop screw to just meet the lever and give it another 1/8-1/4 turn and, then lock it down.
9. Turn ignition off.
10. Turn key to "ON" position and check TPS voltage. Set to .980 Volts (You may have to drill out the metal inserts in the TPS to gain enough adjustment)
11. Turn key off.
12. Repeat steps 1-4 to reset ECU.
13.Drive car as you normally would so that the ECU can relearn again.
During this time ignore the idle rpm. It may take several drive cycles for everything to come together. I have heard from a couple days to around a month before the car started to idle right
