So, I'm thinking I need a new IAC...

[user 66225]

For the last several months, the Trac has been showing signs of wanting a new IAC, what do ya'll think?



-Occasionally, when starting, feels as if it's having a hard time "getting going", takes a bit of gas to get it to calm down.



-When driving slowly, if a small amount of throttle is applied, and then released, the tach gets down to about 400-500 RPMs, feels like it wants to stall.



-And just recently, it has starting "bucking" as described in another thread



I've tried cleaning it and everything else, but I guess 123,000 miles is a pretty good run for the original IAC.



Does anyone have a part number I could borrow?



And, just for the heck of it, :smack:

Since yours is an 01 job 1 you may need to do your intake manifold gaskets. I need to do mine but I have to find the time.

Yeah, was thinking about that too, but figured the IAC was easier and cheaper to swap out. At least for now.

This article will tell you how to test it.

Need a new IAC. Hoping that fixes it and I don't have to deal with the gaskets...



What is the part number for the IAC? Is it different for a Job 1 vs. Job2?



Also, Motorcraft, or does it not really matter?
