Any OBD codes from sockets #2 or #6? The car got an inkling of the problem when the CEL light came on.

LH 2.4 can get a little "emotional". Try disconnecting the battery for a minute or so to clear the adaptive memory, then reconnect.

Throttle body switches are easy to test with a multimeter: three pins, with one common between the two. One circuit should be closed with the T-body closed, the other when the T-body is wide open. This probably isn't your problem, I bet.

How's your crankshaft position sensor? Has it been replaced yet?

You mentioned repairing cracked hoses, how is the main intake hose? Did you remove it completely and check for cracks and leaks? Are all of the vacuum hoses present and accounted for?

Do you have a spare AMM to try?

Any chance you accidentally swapped the connectors for the IAC valve and the throttle body?
