So I did some more testing tonight - I again checked my #9 & #11 pins for the thermistor and verified that the resistance was approx 10K ohms less once the car warmed up, so no problem there. I used my propane bottle to check for vaccuum leaks, but didn't find any. I checked the idle speed motor and it was humming with the ignition on and the car not running. I took off the air filter assembly and played around with the throttle / micro switch. It seems to be closing all the way, I pushed on it as far as it would go and no change, it still idles high. Then, the strangest thing happened - when I was putting the air filter back on (connecting the large hose below the overflow bottle) and moving the wiring harness that goes over the intake, the idle dropped from almost 2K rpm down to 800rpm. This makes me think that something is just loose somewhere, and since I'm only having the high idle as the car warms up, I'm not sure where to start hunting. Any ideas?
