Has anyone cleaned their throttle body? How did you go about doing it? Thanks.

 

Why do you feel a need to do that?

Spray it with carb cleaner, let it dry up.
Start the car.

Honestly, I've had mine out after 25-28K miles and it was pretty damn clean.

 

So you didn't remove it?

That was my biggest concern. If a spray a lot of stuff down there it goes through the supercharger and then on to the intercooler.

 

Yea I had it out when I was doing the BPV mod. That would be a good way to do it.
Carb cleaner is very volitile so it will evaporate very quickly.

If it would make you feel more comfortable you could just wipe out the throat with a soaked lint free rag . Not much to it really.

 

there are lots of ways that cars set idle, and not all do it the same way...

the reason I say this is that cleaning TBs and the assocaited plumbing was a way to get smoother idle because there was a solenoid operated needle valve that set idle speed, and this would crud up and the car would idle like crap.

Now, our cars don't have a cable operated TB, so the ecu sets the throttle angle based on pressure and RPM sensors, so the idle valve is gone. Because it's a compensating design, the TB will compensate for some build up in the bore as things get a bit dirty. And no oil catch can will ever change that. that's because there are a lot of oily vapors that get sucked in naturally. The gas velocities around the TB butterfly are huge, and stuff will get thrown onto the bore no matter how clean the air from the breather lines are.

So the advice is to not sweat it, just wait unitl you're in that part or it's general vicinity for some other job, and wipe it out with a rag with some carb cleaner or the like.....

Erm, sorry if this sounds like a NOOB question, but what other cleaners can you use? And whats a Carb? When someone says brake cleaner, i'm thinking like the stuff i spray on my rims?

The last time i changed out my BPV, i noticed that there was a bit of carbon build up on the TB but didn't do anything about it because i didn't want to screw anything up. ( NOOB, I know...)

 

Carburetor:

Vacuum secondary. I'm guessing a 780.

Geez! Am I that old

I'd find something else to clean my rims. Brake cleaner isn't the best option.

 

And I used to laugh at my Parents...The name that always comes to mind in Carbs (not Atlins either!) was/is Holley!) Had a GTO with 2 4 barrel Holleys and an Eldelbrok manifold! A Long long long time ago!..

BTW: The side of a carb cleaner says not to use it on fuel injected cars for some reason!

 

what is a carb. Spraying brake cleaner on rims. Dude that stuff eats paint, it is a part cleaner.

Man am I that old?

The above is a good 'carb' picture. I guess we should not start talking about the choke now.

Sorry Bster.

 

In the old days,I used to sell Holley carbs.,I think it's 600cfm,model 1850.But I thought SU was the real carb maker!Nowadays,on the West Coast ,CARB is the California Air Resources Board or part of some Diet Plan!Anyway,keep it clean and go fast!
