96 F150 5.8 High Idle... and I've replaced everything! Please help!

The 22k reading is normal.
I bought another sensor and it reads the same.
As you heat the sensor, the resistance goes DOWN.
I think I'll check the connector for voltage. NO sensor connected (if the wire was broken) would mean excessive heat... unless the computer sees it as a failure.
CORRECTION.... No sensor would be infinte resistance which would be the COLDEST indication.

I don't think so. When the IAC is unplugged the engine should idle extremely slow, to the point of almost stalling. You may want to check the voltage on the throttle position sensor again, to make sure the throttle is going to the rest position.

Did you measure the 4.66V across the 2 connector pins with the connector off the sensor?

I double checked the TPS sensor and voltage (1.01 VDC) before I bolted the throttle body back on. The throttle cables didn't move the throttle arm. I opened and closed the throttle and watched the voltage change.
It always went back to 1.01 VDC.
Is the IAC "variable" or is it "two position"?
Thanks again for all the help....
