Default Throttle body cleaning

I'm still not understanding how to search the wonderful How-to-Library. Is there anything in the library on cleaning the Throttle Body? I'm sure I'm not the first person to need to do this.

I thought there was a "How-To" on here somewhere but I can't seem to find it anywhere either.

Some people here I have read just take the air intake off and simply spray carb cleaner into the TB. I have not tried this, mine was pretty dirty so I opted to take it completely off and clean it.

If my memory serves me correctly there are 2 bolts that hold the TB on. Take the air intake assembly apart and remove it, then take the 2 bolts out to detach the TB. There are a few connectors you have to disconnect on the TB itself, but after that it just comes right off. After I had it off, I took the 2 sensors (IAC, TPS) off and used about a whole can of carb cleaner on the TB.

Pull the air intake manifold off, there's 2 10mm bolts. Get a gasket or you'll have a problem like me and be hunting all around because of a strange idle and no visible flaws to the gasket. Pull off the wire, pull the throttle, and there you go. Spray that sucker with some carb & choke cleaner until clean and pretty. Install is the reverse of removal.

It's not good to just spray the C&C into the throttle for a multitude of reasons.

My statement above might be wrong then. I thought some people sprayed carb cleaner right into the TB w/ the engine running. Maybe I read something wrong? Or do they use something else?

On my 2K, there are 4 bolts, but I think earlier models only two. Disconnect the two electrical bundles, the vacumn lines, & the throttle cable (all really easily done). When you remove it, be careful you don't tear the gasket, or you'll have to see the dealer for that. Remove the IAC,(you'll need a torx drive for this,don't remember size)-careful not to loose that gasket either- & then spray the heck out of the body with carb cleaner. Use an old toothbrush to scrub off the stubborn carbon & make sure you spray out the access ports. Also spray the AIC pintle & spring to get all the carbon off there too. Don't mess with the pintle, as it should be in the retracted position & if it extends it can be a bear to get back on the TB. Spray the outside of the TB also to make sure there isn't any grung binding the throttle spring. Reassemble & replace. Should be good to go. You may want to use contact cleaner on the electrical connectors & some dielectric grease on them before reattaching.

...
Experience is something you don't get until just after you need it.

They are T-20 torx screws holding the TPS and IAC on. Or, at the very least, I was able to use a T-20 driver to remove and replace them.

Actually, the best part about the whole proceedure is when you talk about it afterward, you can use "throttle body" & "pintle" in a conversation (ie; " I gave my throttle body a good cleanin' this afternoon & paid particular attention to my pintle) & not be obscene...it just sounds that way!

I'd just take the remaining bolt to the hardware store and match them up.....My local ACE has a great selection of bolts etc.....
