glad to have helped. now just revel in the idea that you didn't spend a lot of $$$ having a mechanic fix it.

the picture I took of it sitting on the paper towel was how it was when I took it off. the other two are after it was cleaned. the top portion wasn't as dirty for me as the bottom was. did you open the butterfly valve and check if there was anything underneath?

I'm hoping that's somewhat good news since it's clean now. Just start a photobucket account. it's pretty simple, then upload the pic to photo bucket and copy the direct link code and paste it between these two things [IMG] [/IMG]

can't wait to see it

If your throttle body housing has metal shavings on the outside clinging to it like magnetite your throttle body is soon to fail to work.

Default Did it!

I had the same stalling issues, eventually it resulted in the check engine light coming on. The local Ford garage tried to get me for $707 for a new throttle body and install. Upon removing my throttle body there was significant sludge underneath the butterfly valve.

The only issue I ran into is that I twisted/snapped the head off on of the T20 screws that held the TPS in place, but a quick trip to True Value solved that issue. Otherwise it runs like a top again, even the idling at stop signs/lights is better.

Can't say thanks enough! If you're ever in the Pittsburgh area on a Friday Night, drop me a line, Lernerville Speedway VIP treatment on me!!

The other thing the local Ford garage told me was that they've seen this issue on several mid 2000s F-150s and a common thread seems to be the use of a K&N Air Filter. Any reason to believe that or just an attempt to add the price of a motorcraft air filter and an extra 1/2 hour of labor?!?!
