IAC could be the culprit.

there is a picture of it here

How much variation in the RPM is there at idle?

I thought of the IAC, but when mine went bad it didn't have a variation in idle, it just died
Of course, that could be considered a variation I suppose.

How often should I replace the fuel filter??? Did it about 10k-15k ago....

I will change it this weekend, better safe than sorry.

I will check the IAC, the page mentioned said something about cleaning....is it worth trying?? How would it be cleaned?? How much is a new one?? Can you get them on ly at ford dealership??

Thanks for the help...

I don't know. Just a thought.

I didn't even try cleaning mine. My dealer charged $144 to install a new one.

OK, money is about to come in to have the IAC fixed... but would this make it idle FAST....like 1500 RPM, and keep it there?? After truck is already warm?? Cruising around looking at houses it wanted to run, Then I was able to "Get on It" on the freeway, and then after it came back down to normal idle.

No, when my IAC went bad my X did not want to idle at all, but rather tried to die if I didn't keep the rpms up. Sounds like you may have a different problem. Good luck with your X.
