Yesterday I pulled the valve cover to look at the harness. I was guessing that I would see fried wires. Nope.... all the wires looked fine and the connection at the grounds bolted to the head looked OK too. So, I started disconnecting and reconnecting connectors. I noticed that all seemed to be fine. I knew the one in question was the round one behind the valve cover so I did that one last. I looked at the ones behind the battery, and the ones behind the valve cover. I checked the distance sensor wiring and verified it's connector. Then I looked at the round one behind the valve cover. Disconnected, it looked OK. I 'deformed' the female connectors to make a tighter fit when putting it back together. Once it was back together I cranked the car and it did idle high at first. After a few starts it seems to be OK now. I did NOT disconnect the AIS connector from the AIS motor. This is something I perhaps should have done since there is only a slight idle float but even that's getting better.
This morning I cranked it and it began to idle fine after only a short time.
One of these days I guess I will get around to rebuilding the TB as I guess it's due with 323,000 miles on it.
