Erratic Running and/or Idling Problem

Erratic Running and/or Idling Problem
Car: 1985 GSL-SE, 74,xxx miles, great general condition.
Situation: Out of nowhere the car will start to erratically idle at approximately 2,000 RPM with the clutch pushed in and rev itself, automatically, between approximately 1,500 RPM and 2,000 RPM with the clutch let out. On and off throttle response is exagerated. For example, slightly pressing the gas pedal makes the car lurch forward while in gear instead of a smooth transition like it should be.
Comments: The car has done this on several other occasions but the symptoms went away almost immediately. When I parked the car it was still revving itself from 1,500 RPM to 2,000 RPM. I left it running and popped the hood. I squeezed the short rubber hose that goes from an elbow off of the intake tube to a metal connection point on the intake manifold or throttle body. Squeezing this hose shut (to cut off the air transfer) seemed to alleviate the problem and as soon as I let pressure off of the hose the car went back to it's said state.
I cut the car off and restarted it only to have the car go to approximately 3,000 RPM and stay there.
Any ideas on what this could be?

Print it, live it, learn it, the only way to get an -SE back on track.
