Issue solved. Was the Cylinder Head Temp Sensor, under the intake, on the passenger side.
30 minutes to pull the TB and intake...30 seconds to replace the sensor. Love me some Ford engineering!
My AC issue is still ongoing, in a nutshell, the engine overheats, ONLY when the air is on, and only at highway speed. Just cruising around 25-30, or idling, it stays frosty cold and the temp gauge stays normal.
If I'm out on the highway or anywhere around 45 or faster, the AC blows cold for about 5 minutes, then gets warmer as the temp gauge maxes out.
If I turn the AC off, it goes down to normal and stays there, until I switch the air back on.
I've put a shroud in (missing when I bought the Expl in March) new fan clutch, new T stat, new water pump, flushed radiator, all hoses, even flushed the coolant in the engine until clean water ran out.
Now, I did some reading on some links google kicked up...anyone ever hear of having the fan clutch programmed? That's what one link suggested, via a Ford dealer.
Another link said some stuff about a thermo bypass that's inside the transmission. No idea why this would make the engine overheat when the AC is on, however.
