Trying to get the idle to work right on this car... It's a new acquisition.

Disassembled, cursed at, cleaned, and reassembled the IAC. No improvement.

Car does now start with a high idle for 2 seconds like it should, then drops from 1500 straight down to 250, then roller coasters up and down.

I have set the TPS correctly and cleaned the TB.

I unplugged the AMM after starting it and all of a sudden, lo and behold - it idles at 750rpm. Granted it's a crappy idle, but it's idling right.

Anything I can check or repair on the AMM? Sounds like it's bad to me.

Thanks,
William

PS I have a 740T parked on the street 50 feet from this car. Can I swap in its AMM?
PPS: Idled consistently after warming up, when I had the idle jimmied up high with the throttle linkage.
