Re: Resetting the ECU
Back the idle set screw off until you can fit a .010" feeler gauge between the screw and the blade; now turn the screw in 1 full turn. This sets the proper air flow past the throttle blade in the closed position. Check your TPS at this point. It should be between .93 and .99 volts, no greater than 1.0 volt. With the IAC plugged in, start the car and let the idle stabilize. This is the proper idle setting for the car.
