88 5KTQ this week my idle speed has gone up

I’ll double check, but the two screws that you removed are the ones  - the whole switch assy pulls off of a semi-circular shaft.  Try some PB Blaster to loosen it up.  Then pry gently from both sides with a couple screwdrivers.  It should come off.

 

Sometimes you need to force the switch adjustment to its farthest position to close and tighten down.  However if when you remove the switch and turn the center shaft hole to closed position and switch does not close then definitely it is bad.  Sometimes the switch is intermittent, in which case should be replaced.

 

LMK if you need one as I have some good ones.

My Idle switch is bad I checked it with an ohm meter and the full throttle switch closes at 2/3 open but the Idle switch never closes. How do I get it out? I removed the 2 bolts but that only seams to be the adjustment.

Jeff,

Did you confirm operation with an ohmmeter?  Did you check for continuity all the way back to the  ECU?

Another short test – disconnect the ISV plug.  Does the idle drop?

I checked the Idle Switch this morning as it goes click as discribed. Today I am going to get some carberator cleaned and clean the Idle Stabilizer Valve.
