I have all those same problems. I have cleaned the idle valve at least 3 times with carb cleaner. The adjustment screw on the valve that you guys talk about, is it a hex screw? Mine is mostly stripped out. When adjusting the screw should the car be on or off? When I pull the wires off the idle valve the car fluctuates at 500 rpms. That is 100rpms slower than normal.
