Warm engine won't idle.

01 GT, been having problems with the engine dying at idle. Starts cold fine, once it's up to op temp, the idle drops to 450-500 and then drops out. Re-starting only if the throttle is held down. I've replaced the TPS, MAF and MAP, cleaned the IAC, IAT and EGR. No vacuum leaks, good fuel pressure. It has given a code of P0327, Bank 1 knock sensor input low. I'm TOTALLY stumped and ready to drive the thing into the bay.:confused:
 


Fixed. IAC mechanical failure. the plunger "ejected" itself on testing. Had to retrieve it from the exhaust manifold. New one from the parts store, Runs like it's supposed to.
 
It happens. Sometimes the problem is so far out in left field, it can't be seen "from the stands" That's why I posted the solution.
