Idle Air Control Valve
After replacing the fuel pump on my starboard engine injectors had a much better pattern but engine would still stall as soon as put into gear. After mechanic inspection he identified the source of stalling as the Idle Air Control Valve
I'm having trouble sourcing the shown part and the only number I can find is on the unit itself: 59559 (and directly under that number is: C0244&)
I did find a part @ AutoZone that looked the same at first glance, tried it and after ECU tried to map it idled at 1250rpm.
Wasn't an exact match it turned out - so I took OEM part to NAPA and they found a part in their warehouse that looked identical but showed fitment exchange for 88-92 vehicles that mostly had 6 cyl. motors not V8. Gonna give it a try, but hoping someone here has some insight into sourcing the actual replacement.
Also, I was told yesterday that when that part gets replaced that a process of adjusting the idle speed is necessary, but no indication of how to do that in a TBi setup. Anyone that can confirm that?
One other question - is it worth the effort to try using some PB Blaster to free up the mechanism on the old control valve?
Any help would be greatly appreciated!!

Re: Idle Air Control Valve
Regarding the first start with the new one there is a procedure for it to learn where closed and open is.......again check on line for your year and engine combo. Seems like the one you put in was staying open and not trying to control the idle speed......which is the job of the ecu. Also check out the crusader parts source for the number then cross that if you want to go to Napa, pep boys , advance etc. I have got stuff from them and it worked just fine.
Make sure the throttle plates and body/ flame arrester are clean.

Thanks very much, I think it's beyond cleaning. The issue I'm finding is several look the same, but very few are worm-gear driven - most are more like a solenoid.

Thanks, that one actually looks like it might work! As mentioned in my reply to Bud above most aren't worm-gears... do you recall whether this referenced one is, or more like a solenoid?
