Ok, here's what i found out: I turned the throttle spindle and I did indeed hear a click and another click as I turned it back. I used the core from my shop towels as a stethoscope on the tps to make sure. I did not mess with the tps screws at all. I think it's good. I ran the engine then pulled the plug on the amm and there was no change in the idle. But let me ask a stupid question:The connector I'm supposed to pull is the one that has the intake air temp sensor on the end? Was that right? Tomorrow I will remove the throttle body and clean it with the proper solvent....(And, yes my Volvo tech is a real one-and he has a known good amm in his shop that he can test with. He just can't get my car into his shop til next week.) Oh also- KGV, you asked about obd codes- still has 232,and the 243 for the knock sensor that has been there since I swapped cylinder heads.
