I just put a motor in my car from the Salvage yard. It runs great. Thing is that it runs really fast (idle). I have adjust the screw on the throtle body (92 VX hatch D15Z1) and got it to run much slower. BUT when I press the clutch it runs at 2,000 to 3,000 rpm for much longer than I'd like it to, then it will eventually slow down. I'm going to go drive it some more. ANY HELP, IDEAS?
