993 Low idle
 I have a 95 993. It runs perfect but the idle is a little bumpy and at about 720 RPM's. When I press the gas on at about 1000 RPM it is as smooth as water. I have cleaned the ISV valve. I have read most everything on the 993 and I know it says the idle is not adjustable. I don't believe it., Hasn't anyone thought of a way to raise the idle on these cool machines? Please help.

hey,
i would advise first to plug the car to check what's going on. your 95 has an obd plug; you need to scan the DME. i'm very confident that it will show the defect part i would also check air hoses tightness all around; did you try to swap the ISV valve with another one? (if you have a 993 buddy) it could be anything from ignition to air or fuel system, so i advise you to get a OBD scan; it will save your time and money cheers |
