Re: how to adjust idle.
With the engine off remove the ISC motor lead,(connected to t/body housing ) start the car without touching the acellerator & await for the idle to settle, connected to the t/body is a small idle screw, adjust it until you get the revs where you want em. Turn engine off & reconnect the lead..
By adjusting the idle you may have to readjust the TPS switch !!
