IAC VALVE cleaning
I just wanted to say that I cleaned my IAC with carb spray and it worked good for about a week. I then cleaned it again and then soaked it with WD40 wile working the valve plunger with a small screw driver. It has been working great ever since.

I cleaned one before with somewhat decent luck, I used some mineral spirits.
It worked fine for about 6 months, then went bad again, so i ended up replacing it.
Its a 30 dollar item, so if you are pulling it out you mine as well replace it.

They are $70 in Indiana
I just cleaned my IAC and throttle body on my Bronco II with STP throttle body cleaner and the truck runs like brand new. It hadn't been cleaned in 90,000 miles so I guess it was due. I highly recommend doing this more frequently than I did. The STP just ate the black crud right off.

Ok, I have never cleaned these parts that go into the depths of the mighty engine. Can you just remove the parts and not worry about the spray throwing things into the engine? I want to clean my EGR ports and Throttle body on my 1997 Ford F-150/ 4.6 L. I know I can take things apart and put them together, but don't want to spray "crud" into the engine.
Thanks for the great forums.

I replaced mine last year 80 bucks from the ford dealer and all of maybe five minutes to change. for that price cleaning it seemed to much trouble.

Hi Orfordcop and welcome to FTE 
You need to remove the IAC to clean it. You can't actually get into it to clean in unless you remove it.
Carb cleaner spray inside the engine wont hurt anything but you dont really want to be blowing junk into it.

I had the same problem with my truck, it would start, then stall. I cleaned the IAC with electrical contact cleaner, now it is workig great. It has been 2 weeks, so time will tell if cleaning will be a good fix. I did not move the plunger while cleaning, i was afraid to damage it.

Well I cleaned inside the EGR valve and the Throttle body area. That was two weeks ago and I thought I was all great. The light was off, no more p401 codes. Now tonight I am going fishing and the dang light came back on.
I'll have to wait until tommorow or the next day to get the info on the light code.
I'll keep you all posted.. Just think I never had this much trouble with my Dodge Dakota.
I am trying to stay a good loyal Ford fan.
