I had the same symptoms with the throttle switch on my 200.  Per S
Mockry, if these are the original generation design, they're pretty much
guaranteed to be bad, and most likely intermittent.  IME he's right.

After being wakened from an early hibernation (June to Novenber) I put
Max ('87 5KTQ) back on the road today.
3/4 of the way through the 150 mile shake down cruise, the idle jumped
3000 rpms and stayed there for the duration of the trip. The good news
that the rest of the trip was all highway, and we made it home without
further drama.. almost like cruise control.
Unplugging the ISV had no effect, and I could find no visible tears or
intake leaks. On getting home, I removed the ISV which proved to be
and a manual inspection of all available lines proved fruitless.
I followed this with the WD-40 spray test of all known potential leak
points, hoses, lines, gaskets, valves, etc..."idling" at 3000 rpm. No
I was kinda hoping to take Max to work tomorrow, Any ideas or BTDTs
would be
