I just replaced the AMM which was a previous problem but knew that if you unplugged it the car would run. Anyhow, i just bought two AMM's from fleebay and plugged them in, they were apparently were tested and were good, they look nice, with inner wire web intact. Anyhow I've tried both of these and neither one of them fixed the issue. So in a nutshell, with the AMM plugged in, the engine idle comes up and drops immediately to stall. With the AMM unplugged the engine will run, but idle hunts between 2-3k rpm. So I'm confident in thinking that the AMM is not the problem. What else could be the issue? what about the throttle position sensor?

Thanks in advance,
John
