Quad-4 (1228707 ECM) Rough Idle Problem

[david garnier]

Hello,

I haven't been paying all the close to this thread, I
appolgize if I am off base...
I have seen rough, unsteady or idle that never seems
to smoothly come down, until maybe the engine starts
to warm up.  Dumb question, when was the last time
you removed your IAC and cleaned the pintle and
mating seat with gas or cab cleaner?  I am amazed at
the difference cleaing the pintle and seat will do on
idling.
