Cleaning the throttle body
I have a 1987 F-150, 302 with fuel injection. It has a high idle problem that is caused by a worn or gummed up throttle body. After reading this site, I have learned that this is not exactly an uncommon thing with Fords...especially if the throttle body was cleaned with a non-Ford cleaner.
I have just found out that new throttle bodies are expensive...
Anyway, I was thinking I could get by with some regular cleaning of the throttle body, and a stronger spring to bring the throttle back to the idle position.
I am not much of a mechanic at all, but really would like to take a stab at removing the existing throttle body, cleaning it, and putting it back on.
Does anyone out there have any pointers?? Any recommendations on the cleaner to use would also be great!
Also, if this is an area where a rookie like me shouldn't be messing around, please let me know.
Thanks!

Cleaning the TB is totally easy, because your year didn't have any protective coating. Just take it off (have some plugs available for the coolant hoses to/from the TB) and clean it with carb cleaner and a brush. You might want to re-lubricate the butterfly bearings and linkage, the carb cleaner removes everything. Don't forget to take off the idle air control (IAC) valve and clean it thoroughly with carb cleaner as well, while you're at it. You may want to get the TB and IAC gaskets, just in case you happen to damage the old ones during removal.

Hey bjoern, I was looking at your pictures in your gallery, and noticed
that you had an electric fan installed with the orig. fan shroud,
was wondering what type of fan you had, and if it works okay,with it
being a single fan and all,

I have an 88 F-150 with a 300-6 in it. I will be putting some #19 injectors in my truck along with a restrictore plate. Do I have that coating on my throttle body? I'm a manager for UPS and one of the mechanics at my center said to leave the throttle body alone, but brake cleaner will work great on the upper intank manifold. Alot of our smaller trucks run 300-6s in them but when he replaces them he gets a new complete crate engine efi and all. Maybe in 88 they did not use the coating?

I'm pretty sure the 88s did not have that coating on the TB (mine didn't). There should also be a sticker somewhere to not clean the TB if you had the coating.
As to the electric fan, check out my webpage, I have a detailed installation description on there.
Let me know if you need more specific info!
