The walls of the throttle body are dirty, scaly.. looks terrible. The injector is rusty under the wire plug. I am thinking I need to pull this off, clean it up, and reattach with new gaskets.
How do I go about doing the clean up? I do not want to damage anything (especially the once-shiney walls of the tb, do not want to damage..). Are there proper solvents or something I would use to clean it out? I looked for a new/rebuilt throttle body, but I am not sure anyone sells them anymore.

Also looks like the connectors that plug into the injector is a bit melted.. this car already has had a fire, albeit a small one.

Thought this picture would be worth as many words..

You take it apart and soak the parts and they come out looking great.

Well the aluminum ones that is. Not so sure about the steel, however that rusted nut I am sure you could find a substitue for.

TBone I have a good t-body from an 85. It was running good when I removed it from a blown engine in 2007. It might be better to freshen up than a toasted one. $20.00 + shipping.

Does "The Raptor" come with the TB?

Thanks josef- I will use that as my "backup plan".. I will try and clean it up first, mostly based on the "I have never done it before and want to learn how" principal. However, if it does not work, I will hit you up for that intake setup.

They're easy to rebuild, there's a kit made by GP sorensen, part # 96-617. I've rebuilt two now (one on car and one spare), makes a great difference in the feel of the car. Remove the IAC and TPS before you start. Use a can of carb cleaner, a toothbrush, a heavy wire brush, and a wire wheel on the end of a drill or bench grinder. Spray out all the vacuum lines, run a pipe cleaner through them, followed by compressed air.



Despite what the manual tells you, the fuel pressure regulator IS serviceable, and comes as part of the kit. Unless you're a girly-man and can't compress a spring and tighten a couple screws at the same time.

Nope, Raptor not included. Grandchildren would scream blood murder

I've always resorted to media blasting to clean up metal parts. Having a booth and a media recovery system is nice, but it's not necessary. Media blasting cleans parts very quickly and all you need is an air compressor, a $20 gun and a $10 bag of the right media for the job. (Oh, and a pair of goggles and a paper face mask). Some machine shops or body shops may even let you use their booth for a small fee. The media you use depends on the type of metal you're cleaning. For steel parts use either silica sand (cheap but not great for your health), or medium crushed glass ($10 for a 40 lb bag up here). For aluminum, there's lots of products like crushed walnut shells, baking powder, or glass beads to name a few, but I just buy a bag of fine crushed glass (looks like fine sand). As long as you don't direct the stream at any given place for too long, then you won't have any problems ruining the smooth finish on the inside diameter of the TB. Here's the before and after pics of my N* throttle body from my build thread to give you an idea what can be accomplished.
