88 5KTQ this week my idle speed has gone up

[LL - NY]

You'd be best to unplug the switch and check using a continuity tester at
the switch terminals. The click is a mechanical function of the microswitch,
however those switches have a reputation of electrically failing unless you
have the later updated switch. Same goes for the full throttle position of
the same said switch. Go to www.sjmautotechnik.com and go through the entire
"secrets of high boost" set of pages (including the maintenance section) and
you'll have a better idea on how to check out your car's systems.
