throttle body
i have a duel throttle body from my 94 f150 & i saw a factory sticker on the side saying not to clean it because i can cause it to have problems.....there is a rubber hose from the valve cover breather to the air intake hose & i think that is why my throttle feels sticky under acceleration from a standing start because of the oil build up on it........what can i use to clean it & lubricate it or is that not a good idea & i will ruin it & just was wondering about what the inside of the intake manifold will look like when i take off the throttle body & the egr connected to the side of the manifold...........any help on this is appreciated...............thank you.................

The warning is so you don't remove the dag coating. If you do, it can cause a high idle. Here is an article explaining the purpose of the dag coating inside the throttle bore. Even though the article is about a GM throttle body, Ford also coated the inside bore of some of their throttle bodies.

If the throttle body shaft is worn out, there are companies that install bearings to support the shaft.
Probably cheaper to purchase a used throttle body.
If you want to clean out the intake manifold go the auto part store and get some Seafoam. Follow the instructions on the can. Some people disconnect the power brake hose and use the hose to suck the Seafoam in.
If you have a lot of carbon build up in the engine you'll see a lot of smoke coming from the exhaust after injecting the Seafoam.

The tube going from your valve cover to the air intake box is part of the PCV system. Clean air goes in there and comes out on the PCV-valve to manifold side. There shouldn't be very much oil that leaks out of that tube since it's purpose is to bring air in.

Here's an example of a company that installs bushings for the throttle shaft.
I've never had it done but it appears $65.00 and up is the going rate + shipping. This company appears to charge $85.00 for a throttle body bushing install.
They mention they want you to unbolt the base portion of the throttle body and only send in the lower part that contains the throttle body shaft.
Disconnect the throttle/cruise control linkage at your throttle body and manually operate the throttle body linkage. See if you can determine if the binding is coming from the throttle body shaft.
