[T3] Runs Great....but very hot...

[J. Jonik]

This is about T 3, 71, Std shift.     ...the one that had endless Fuel Problems that seem to be now fixed by a hundred adjustments and tests, unhooking Cold Start, Changing the Control Unit and so forth.  The Temp Sensor in the Air Distributor is also unplugged.   If I plug it back in, it runs kind of rough.

It's been mostly fine for months...except one thing...Idle would, at any time, stay high for a while.  Then later, hot or just warming up, dip to low enough to flicker the oil light. While driving it was fine.  It never stalled.

The other day, on a hunch, I changed the Pressure Sensor...and now the idle sits right where it should...no more highs and lows.
 Does that make perfect sense?

One problem left.   After maybe 20 or so miles, highway and in town, the engine is really hot...hotter than it should be.

What's the list of probable reasons for the heat? (No...there's no rags in the air ducts.)
