The two little nylon gears in the Idle Air Motor (IAM) have partially
stripped, and its all the one assembly. The gears are of course not
available parts. I have to wait about 10 seconds for the CEL to go out
before I try to start the engine, or else it stalls immediately. Second try
is OK. When decelerating throttle closed, the engine jerks when the IAM trys
to compensate and hits the stripped region of the gear set. Its an
irritation rather than a major problem. I found a 93 4G64 SOHC 8v part, but
its not the same (smaller verturi size, different IAM parts)
New replacement of throttle body assembly is around $400, I've been offered
a Galant part for $75.

Idle Air Motor, is that the same as an Idle Stepper Motor? it attaches with
two bolts and a 35mm o-ring to the bottom half of the throttle.
i have found this to be interchangable between early 90's 4g63 (60mm
throttle), late 90's (52mm throttle) and japanese domestic market "cyclone"
(60mm throttle)
it seems to be fairly universal in it's application, you should be able to
bolt it up and be done.
the seals are also unavailable from the factory. i have found throttle
shafts at applied technologies (chicago rawhide part# 3930) for $4.22 each.

Hmm, I seem to recall that when I had mine off it was an integral casting.
I'll double check when it gets warmer, and if the 4G63 ISM is the same, I
can get one locally.
Thanks!
