EDIT: it also seems to do this frequently in the summer. again, nothing to do with the actual engine coolant temp. i got off the tollway today and it was idling at 1000rpm with the a/c compressor on. engine at 80c. idle went back to normal after driving on some neighborhood roads...

Most of the Fuel Injection Pump is lubricated by the Carnkcase Oil From the Engine. Only the Fuel Injection Pump Elements get any lubrication from the Fuel.
You did not comment on this but I will include it here. The is backed off/out and then the idle speed is adjusted. After that the Rack Dampner/Governor Idle Pin.
The Rack Dampner/Governor Idle Pin is not supposed to effect the idle speed much. Meaning that you idle adjustment should not be hanigng on the Rack Dampner/Governor Idle Pin.
Besides the sticking Linkage Balls, Accelerator Pedal Linkages, The Bell Crank on the Fire Wall there that Plastic Cam on top of the Valve covor.
At the Bottom Rear of the Fuel Injection pump is another Springt that goes to the Throttle Arm and a Bracket that Bolts onto the Block.
