Hey guys!

I recently cleaned up my throttle body, which also included cleaning up the IAC. I had no problems taking it apart, simply put the computer into it's code setting mode, which forced it out until it simply popped apart in my hands. However, I can't seem to get it back together, lol

Is there some way a guy can reverse the poles of the connector so when I set it into code mode, it'll suck the IAC in instead of spitting it out?

I have no idea how the stepper motor works, and I don't want to guess and test, just to wind up burning it out... New ones are not cheap around here...

 

normally you don't want to take them apart to clean them.
fully extended is good enough.

but now that you have it apart & clean, take some WD40 or some other light lubricant & spray on the threaded part of the shaft & in the housing where the shaft goes, now properly line up the shaft in the housing & push it in.
the shaft will only go in one way for it to work right, notice the groove cut into the threaded part of the shaft, if you line it up wrong, it will damage it & you will need another one.
a little side to side wiggling & light twisting of the shaft while your pushing it in may help to get it back together. you don't need to push it in very hard, normally about 10 or so pounds of pressure is enough.
if it goes back together, you should be in good shape, if it doesn't, then its time for a new 1.

 

Well, I ran to the junkyard, and got myself a TBI IAC to experiment with. I found that if you switch the blue wires with the green wires with the same colored stripe, it'll suck the IAC plunger in!

Far better than trying to wiggle it in myself, thats for sure!

Truck is already far more responsive off the idle with the IAC working, though that thing certainly does make a whole lot of noise now! Probally just way out of adjustment. I had the throttle body idling at 800 RPM without the IAC helping, so I suppose I just need to let it get to full temp, then adjust the butterflies till the IAC is showing 15 - 20 counts
