Hi Idle is usually the Air Flow Meter (EF & EC-150) or the Idle Switch (EF & EC-174).

Right-Click the link below, select Save As, and save it to your My Documents folder:

d21_truck_1989.pdf

It is for the 1989, but it should be identical to your 1986.

The ENGINE FUEL & EMISSION CONTROL SYSTEM (EF&EC) is what you need to turn to.

You should start by reading the DIAGNOSTIC PROCEDURE (EF & EC-41) then attempt the SELF-DIAGNOSIS (EF &EC-71).

If you flip through those sections, you will see that #11 on EF & EC-45 is about Abnormal idling - high idle (after warm-up).

There is a big checklist of simple things to look for.
