4k high idle

[Ben Swann]

Bad Idle switch or defective ISV or possible vacuum leak.  Usually the idle
switch.  Need to remove the Throttle body, but if moving throttle off idle
and don't hear a click then you know.  Otherwise a continuity check is in
order.

A young guy at work picked up a 4k that runs but not well. It idles at 2500
RPM unless he unplugs the FPR on the fuel distributor. I gave him 2 idle
stabilizer valves but no change.

What are the usual suspects on these non turbo cars?
