I believe that when the engine is cold it idles at a higher RPM than when it is hot. Mine does not. Never has. So I've started replacing and checking different items. I've replaced the Cold Start Valve and now have moved on to the Micro-Switch. It seems fine but here is the question. It appears that a capacitor has been spliced into one of the wires going to the micro-switch. The capacitor is anchored next to the micro-switch with a screw into the top of the inlet manifold. Not sure this is right but the wire is burnt and needs to be replaced. Don't know what size it is or what the part number is. Can't find anything on it. Any ideas?
