Message like conzult, datascan.. etc..? they might help narrow it down.

Well I've got to say that you've really given it a good go a fixing...

when you say the mechanic changed the temp sensor was it the ecu or gauge unit?
have you tried another TPS unit? or re-adjusted your one?

how does the car run with the MAF disconnected?

have you checked the wires to the O2's, could be damaged.

best of luck.
