Hey guys...I'm pretty much getting the runaround about being able to reset the IAC motor on the TB...and was just wondering if anyone could post the page out of the dealer service manual (or a link to it) that says the IAC is resetable???
They wanted me to pay $90 for a damn diagnostic check, when I already told them what the problem is!!! On top of whatever it'll be to fix the IAC, they probably would've told me to buy a new one from them! All they want is our $$$!!!

I have a friend who's a master mechanic at a local Mitsu dealership, and when I replaced my crankshaft position sensor, he hooked up a scanner that has a special IAC and "re-learn cam/crank" screens. I didn't really see the whole process, but I guess their scanner can "synchronize" or allow the ecu to "relearn" the "new" part. I suppose it's like recalibrating it electronically. I try to get a hold of him to find out more about it.

just unplug the battery for about 15min and let it reset. then when you hook it back up, start the car and let it idle for about 15-20 min. if you want to pay somebody to reset it, take it to pepboy. they will do it for $50.

ya their diagnostic fee is ridiculous. i've gone in before and told them exactly what's wrong and exactly what they need to do and they're like "well we still need to look at it and figure out the problem.. it'll be about $100 diagnostic fee" fuck that. i wouldn't normally go to them for anything but i need them to flash my ecu for the stupid secondary air crap on the 95's... unit was removed but ecu wasn't flashed so i have a permanent CEL... for $100 i can live with it.

This is how I reset mine and it worked perfect... Do a search and you'll see my 50 posts about IAC crap.
Phase 1 -Unplugged IAC -take IAC off throttle body -note: some people will argue this is not right, but I have done it and read it in many other posts. Pull out IAC plunger (with your hands, -not to hard) until it brings up and wont pull out any furthur. -clean it with carb cleaner/intake cleaner -place the plunger back in the hole untill it brings up in the By pass canal (i made that term up) -slowly force the IAC motor towards the TB until the they are snug and the O-Ring (get a new one if possible) is squat nicely. -put your screws back in to tourque spec (haha) -start the car
One of three things will happen now, a)the car will stall b)the car will rev very high (how high? it depends) c)it will work perfect
If A Occurs - remove IAC - very gently push the IAC plunger back into the motor itself (1/64") - put it all back together - start the car
If B Occurs repeat PHASE 1
Once it is to the place where the car idles perfect turn it off un-plug the battery, and wait +15 mins. Reconnect the IAC Wire, reconnect you battery and give it a whirl.
I did this 4 months ago and the car has idled and worked perfet since.
