High idle after Street Holes only 1996 Ranger 2.3L

Hi guys,
I've read all possible thread on the internet about high Idle.

No one seems to have my problem.

I drive a 1996 Ford Ranger 2.3L, it's "almost perfect" (not true, :D but....)

I'm italian but I live in Dominican Republic, where the pavement road is full
of deep holes.

Every time I drive over a hole and the truck receives a hit from it,
the idle rpm go to 3000 (if I press the clutch or if I stop at a trafficlight).
It slowly goes down to normal...
BUT it ONLY happens after I "hit" a street hole.

I tried, when parked with engine runnig, to hit or moove many parts of the engine to
find the guilty one... but I can not replicate the problem myself... and...
when driving it's impossible to check inside the engine...

Any ideas?

Thank you,

Hmm..possible loose electrical connector or shorted wiring? Throttle cable binding? Possible bad IACV valve? Those go bad frequently so wouldn't be bad idea to replace it
