I'm going to pull off my throttle body soon, to clean it. Anything I should know before removing it, such as any part of it being tricky? And should I need a new gasket, where can I aquire one? Thanks in advance.

I'm not sure your TB needs to be removed to be cleaned...
 
What are you going to clean? Just the bore and butterfly? Just take off the intake piping and have at it with some specific fluid..

Precisely. I thought that it had to be removed to do that properly though, so that all that garbage doesn't make it's way to the valves and such. Plus, I figure I can do a better job of it by actually removing the thing.
 
hey buddy they put air filters on cars for a reason. I'm sure your throttle body is as clean as the day it rolled off the line.
 
I had mine off today takes like 20 minutes. Definately get a new gasket from dealer $12. The 2 auto parts didn't stock them by me. You need to drain your coolant and disconnect the coolant lines on the throttle body 2 nuts 2 bolts and disconnect tp sensor and iac sensor and thats it. I was surprised at the difference cleaning it with carb cleaner made. I have a turbo with Haltec and run extremely rich so there was alot of gunk in there. Straight razor blade to get the pieces of cheap ass gasket from throttle body and manifold.

While you have access you can unbolt your egr valve from right under there too (easy access with TB off) 2 bolts then I think 4 screw hold the sensor to the valve.
Theres a how-to or something here just look up egr.
Have fun!

Every engine experiences EGR residue and slight misfire on occasion and the throttle plate will cake up with that soot over time. Just take an old tooth brush and carb/throttle body cleaner and scrub and spray it down. But remember that when you try to crank it up, the check engine light may come on and bring up a misfire code, so be prepared to take it to your parts store to reset the light
 
If you remove the throttle body you will loose a little bit of coolant, but for me I didn't have to drain the coolant at all. Just top it off when you're done.

It's much easier to follow Blackshine007's advice and toothbrush it.

And I would also suggest cleaning the EGR valve as Shane02Pro5 mentions.

Why bother? Just pull the neg. battery cable, wait a few, pump the brake to dissipate any remaining charge in the system, and reconnect.

ECU will be reset and cleared of any CELs (unless you have other issues...an entirely new thread in and of itself there...).
 
dont reconnet the coolant hoses too!

oh and if you're really insane like me, get a dremel and remove the nasty little bump near the butterfly plate and sand and polish the inside of the TB. mine's like a mirror now :D hehe

Your own porting / overboring job!

Any problems after doing this?

Any differences that you can tell [sound, performance, etc...]?
 
probably no difference, but i had the time so i thought why the hell not.

no problems at all afterwards. i didnt touch where the plate sits on the inside of the TB.
