Hi, does anyone know how to set the base idle on a 4agze (aw11) I am having trouble with it occasionaly stalling and the idle rpm seems to vary a lot. I should also note that the idle air bypass screw is all the way in to get the engine to idle low enough. I will try and test the TPS and ISC valve tomorrow, but I'm not sure if the throttle stop is adjusted correctly. Any help appreciated.
