Cleaning Throttle Body
Guys,
I took my throttle body off on the '93 today to replace the TPS and the back side of the TB and the intake manifold has a lot of black oily residue on it.
The TB has a sticker on it saying not to clean it and I've had one other member tell me not to clean it.
So what should I do about the crud in the TB and manifold?
Why should the TB not be cleaned?
Thanks,
Rob

I sucked Seafoam through my break booster line to clean the carbon deposits out of the throttle body. Check out my vid:

It's real easy and gave me a bit more throttle response.

Chris - I seafoamed mine a couple of weeks back and it made a WORLD of difference.
But - the brake booster vacuum hose is well downstream of the throttle body on my engine - not sure if they are all that way.
It seems so simple to spray TB cleaner on it but I don't want to screw it up.

If you guys are talking about "Seafoam" that comes in a white/red Can it works great.
I fill up the front tank all the way then dump a can of seafoam in the tank
idol Response improves big time.
Then do the same with the rear tank.

The reason you're supposed to be selective about the chemicals that come in contact with your throttle body is because there is a thin 'liner' inside your TB where the butterfly valve shuts. If you use a chemical that eats that liner, your butterfly valve will not seal properly, and you'll soon be buying a new TB.
FWIW, I just cleaned my upper intake last weekend. I let my TB sit in mineral spirits for a day and a half, and now I have a very pleasing 700rpm idle that I didn't have before. So, be careful what chemical you use, but there is some room for experimentation.
Also, I used to twice a year take a toothbrush and a can of deep creep or TB cleaner, or whatever, and scrub away while the TB was on the engine. That might help a bit, too.
