Re: 2001 Mercury Sable - Nearly stalls when starting cold

Click for full size
Thanks for the help thus far everyone.

I took a closer look at the IAC valve and throttle body. The IAC did look to have some carbon buildup that could be preventing it from functioning properly, but I didn't have a chance to get a picture of it.

I also removed the air intake from what I believe to be the throttle body (don't know much about what I'm doing, but going off of the help here as well as searching Google) and it looked clean to me (see attached...)

FWIW I have cleaned the TB on a Taurus multiple time using that cleaner without any ill effects. No swelling, no sticking. I know a lot of people (taurus car club) who have done the same.

Why don't you take the air intake hose off of the TB and take some pics of it, including with the valve fully open so we can see what the backside looks like. Take some of the IAC as well with it off the TB.

No, I hadn't heard of that. I don't even think my Duratec had a gasket on the IAC. The first time I removed it there wasn't one and I never had any driveability issues. The mounting surface was shaped in such a way that it looked like it would provide some kind of a seal. I've seen some people mention the presence of a paper gasket but never any redesign or aluminum spacer.

The engine in question is a Vulcan.

I know. I haven't ever pulled an IAC off of a vulcan before so it could involve a different gasket/mounting setup.

Will do.
Can't tonight, but I should have some pictures up by tomorrow.
