I just checked the RockAuto web site and found that there are 2 IAC valves listed for my 2001 Explorer sport. called their toll free number and the guy didn't know the reason. He checked the Motorcraft web site and said it had to do with the VIN number. I gave him the number(learned to carry the top page of my insurance policy around with me) and he wasn't sure anyway. He recommended I contact my local Ford dealer to find out what the difference is. Something about the 8th digit. Asked me if it was an "x". I told him it was an "E". He still couldn't tell me which one to buy. Any ideas?

Taras,
From what I have found, it was dumb of him to ask about you VIN because all of the 2001 Explorer Sports had the E as the 8th digit. I looked on a few websites that I go to when I have this dillema, and I found that the two different IAC's have to do with the manufacture date of your vehicle. It seems they switched the IAC on the Sports manufactured from 7/24/00 on. Motorcraft pt.# CX1791 is for Sports manufactured before 7/24/00 and pt.# CX1915 is for the Sports manufactured after 7/24/00. You can find your manufactured date on the sticker inside your driver side door jam. Also, Ford sometimes puts the Ford part number on the part itself. Take the IAC off (it's really easy) and you can then go to Motorcraft's website, click on Interchange Guide, enter the Ford part number and get the Motocraft number that will match one of the two on Rock Auto's website.

Hey there, try the mass air flow sensor and the relays. The relays are located under the hood on the passenger side next to the firewall in the back corner. They are in a box that looks like a fuse box. The best person to talk with is wolfmeister. He has several threads working and seems to have a very good working knowledge of the explorer. Good luck, Bo

Greetings,
I have a 2001 exp sport and just changed the IAC 2 days ago. No change.
It starts immediately, revs up to 2000 rpm and gradually(about 1 second) drops to 1000 and in an instant I have to gas it to keep it running. Once it warms up it's good for the day. To warm it up I have to sit in the truck about 10 minutes and keep it from stalling. Afterwards it will idle by on it's own. Needless to say, this is a pain in the winter.
Any other suggestions beside the IAC.

Greets RTREV64, I cannot help you with IAC PN's as it has been a while for me.
But,
I would try to deal as direct with napaonline.com as you can (email or call them) .
Or perhaps someone reading this blog can add in some help.
It's likely that your 99 ford ranger gets a different PN than my 99 Explorer,

IAC 98 ford exployer IAC replacement needing gasket?
I had the classic symptom and sure enough this was the fix. I purchased the IAC from Pepboys and it included a gasket. My original part did not have a gasket but rather used two round o rings. I replaced the part without the new gasket but now I wonder if that was the right thing to do? The Hayes manual said to apply some motor oil on the o rings with no mention of any gasket...

I can't see your parts. But I do have a background in engineering vacuum seals for high vacuum thin film coating equipment. In order to use a rubber O'ring, there must be an O'ring groove for the O'ring to sit into. If you have this with the new parts, then O'rings are the right way to go. You must have a 1/16 or at max a 3/32 diameter cross section O'ring. You should have .03"-.04" of the O'ring sticking out of the top of the groove before assembly. If you don't the O'ring(s) could be too compressed to make a seal. You can get black Buna-N O'rings at pepboys... You can probably get one to fit. Or try ACE hardware - you know they are the place with the helpful hardware man, right? Acutally ACE helped me out with an o'ring I needed on my rig so I can only applaude them. As far as oil, sure standadrd motor oil is OK for this application. It justs needs to gliscene - not drip with oil.
