The proper way to adjust the idle screw is to back the screw out until you can slip a .010" feeler gauge between the end of the screw and the stop plate. Once you have this .010" gap, remove the gauge and turn the screw in 1 and 1/2 turns. Set your TPS to about .95 volts after doing this. You may need to elongate the holes on the tps so you have room to turn it. You can't just swivel it on one screw it has to turn. After doing all this, reset the computer as PKRWUD already described. After you hook up your battery, start the car and let it idle for 10 minutes with all accessories off. Turn the car off for a couple minutes. Start it back up and let it idle for another 10 minutes with all accessories on. Go for a test drive.
