I removed the air filter housing and started checking electrical connections to items such as EHA, idle control valve, and air flow meter. None of them seem corroded, but I did wipe them off. It didn't seem to help. If I adjust the air flow meter the revs come down, but then it idles pretty rough so then I turn it back up slightly. However, if I turn it off and let it sit a minute, it has a hard time starting unless I increase the fuel mixture.

I am not sure if I check the items you mentioned in your first reply. Where are the, "throttle valve switch (idle and WOT circuits) and linkage microswitch for proper function" located? I am not to savy when it comes to knowing car lingo.

Again, I appreciate your time and help.
