Zoran:

Fore and aft (predominately)

I forgot to mention, the Hyena is an '88 Westfalia with a 2.1 WBX.

After I was on the road for 10-minutes, I had to stop for construction.  While stopped, the idle climbed to ~2000 RPM and pegged there.  I tapped the fuel feed pedal and it momentarily dropped to normal and then climbed again.  I tried tapping the pedal a few additional times and had the same result.   Interestingly, when I let the clutch out a little and put a but of load on the engine, idle dropped to normal and stayed there .... until the next time I stopped.

Is it possible that I have loose/worn transmission or engine mounts which are allowing enough play to affect the throttle at idle?   The reason I ask is that when driving (even on our trip home) in fourth gear, I can feel/view ~1.5-2" of movement in the shift level when I take my foot off the fuel feed while driving.  In my '66 Westy there was always movement - greater than in a car due to the length of the shift linkage and shifter - but not this much (I realize this is an apples and pomegranates comparison, but it's my only point of reference ... other than the test drives I conducted in other Vanagons).
