yes, I have looked but it didn't seem to be any problems with it that could see without taking it apart.

Only while driving is when it seems to stick and very seldom does it stick while idling. It sticks mainly while I'm in 2nd going to 3rd.

.....just noticed you said sticking OPEN .... oops

That's ok. I checked everything at least twice. The WD40 seemed to help alot so I'll try it again tomorrow and give you guys an update when I can. Thanks you guys it's greatly appreciated. The first engine I had done this and I ended up getting a new throttle body from ford to fix it.
