Intake Tb cleaning

[Bud92gsx]

Can I just spray Some carb cleaner through the tb and clean the tb and the intake manifold?

Try and keep the TB open with one hand and spray it down with cleaner and wipe all the grim/black away with a nice clean rag

If the carbon buildup is bad enough, carb cleaner won't even scratch it. The only way to really clean it is to take the manifold off and have it hot-tanked. I did this last year to mine. At work we use some foaming throttle plate cleaner that just eats carbon buildup (I've used it to degrease engines) and I let about three cans of that sit in the manifold for a couple hours, scrubbed as far in the plenum and runners as far as I could with a wire brush, then sent it to the hot tank, then RE-foamed it and scrubbed it and there was still carbon in some of the nooks and crannies.

The throttle body, on the other hand, is a lot easier to clean. You don't even have to take it off to get both sides of the butterfly cleaned. Be careful, as there are some ports that you don't want to get chemicals into, and you don't want to mess up the throttle body shaft seals.

I cleaned my tb when i rebuilt it. Took sensors off and put it in a big bowl of purple power and scrubbed with plastic brush and pipe cleaners. Worked great and for the manny, i have no personal experience.

The only proper way to clean a throttle body is to take it apart and glass bead blast it

I am assuming your name is steve?

But that is a pretty looking TB. I wish soem of my shit was that clean. I am in the process of cleaning it up, Anyone used the chemtool on it?

While glass beading does wonders for the external surfaces it doesn't help much with the internal passages besides plug them. A combination of chemical and mechanical cleaning is usually required.

Try seafoam deep creep its an aerosol and just spray the plate and down into the intake manifold. It has worked wonders for me in the past and never gave me any problems.
