I've got a 1990 244 that runs real rough. It is only driveable when the AMM is unplugged. I've tried three different AMM and have the same results. It wants to die at idle, so I removed and cleaned the intake (it was pretty crapped up)and also cleaned the IAC valve. I tested the IAC by giving it 12v's, it works. I then tested the plug with my DVM. I read 11.88v with no pedal, it read the same with the pedal pressed. It's my understanding that when the pedal is pressed that the 12v should stop. Right? I'm kinda stumped, I think I've got two seperate problems. What are my next steps?

Stumped in Ohio
