IAC issues

2004 crew cab LS. Runs great cold. Once the engine warms up the idle drops, oil pressure drops(at guage) and it stalls.
Been in the shop for 3 weeks. OEM IAC was bad, I replaced with and aftermarket - it was bad, they replaced with another aftermarket - also bad, ordered and installed an OEM, ran ok to start and now also appears bad.
Web lore shows this problem as common but no clear remedy - save for a 'For Sale' sign. Perhaps the feedbacks to the ECM are making the circuit overdrive the IAC? Any help would be greatly appreciated

Not possible to have that many bad parts.

There is a control issue that is being overlooked. You need a shop with expierence in this type of repair to find the exact failure.
