Throttle Body Cleaning???

[Rookie]

Alright basic question... Does the throttle body really get dirty??? I mean that dirty that taking it apart and cleaning it gives you a noticeable gain? And if so where can I find directions on how to clean it.

[frank de jonge]

Just remove the hose to the throttlebody and start cleaning it with WD40.

Btw if it was really dirty you can feel that the trhrottle response is better when cleaned it well..

I did it last evening. Runs very smooth now

It does get very dirty. Every month or so you'll find there is a build-up of some really oily black greasy stuff. I clean it out with a tooth brush.

here is a picture of it, remove the clamp from the intake hose and you'll see it

in the picture I have everything removed because I'm trying to get to my Idle Control Valve at the moment.

Are you guys sure it's okay to take wd40 and spray it all over the inside of your throttle body?

[kestrel325is]

If you're not comfortable using wd-40, you could use Brake Parts Cleaner, or b-12 Chemtool. That stuff is awesome.

The brake parts cleaner costs about $1.50/can from the autoparts store.

hope this helps.

Doesn't Gum-out make a throttle body cleaner? It's prbably the same things as card cleaner though.

I believe so.

In my oppinon, I wouldn't recommend using WD-40 to clean the throttle body. I work on jets in the Navy and we use Isopropyl Alcohol for that type of cleaning. It evaporates quickly and won't leave any residue like the WD-40 would.

[kestrel325is]

that would be my concern, too.
I would just stick with the Brake Parts Cleaner or B-12 Chemtool. Evaporates fast, no residue.

[wulley1]

IPA is good stuff, but does leave a slight residue. I work for a semiconductor company and we usually clean tools with acetone, then IPA, followed by methanol. When finished, any dirt or oils is washed away and everything is 100% partical free

[Robdrmer1016]

When you clean the throttle body do you go inside? Like open up the flap and spray in there or just spray the flap and clean it?

[leobmw]

dont mean to change the subject, but if you replace it with a Dinan one. do you get any mayor gains in performance considering my car is 92 325i pretty much stock(chip).
And buy the way how do u clean it just the flaps or inside to?
