Throttle Body Cleaning

Just had a Jeep mechanic tell me that my throttle body and plate are filthy. So I'm going to unbolt it and hit it with some throttle body cleaner spray and a tooth brush.

But

What else should I look at? The intake manifold? It's made of plastic, I wouldn't feel good using abrasive solvents in there. Any suggestions? Or just a new air filter and throttle body cleaning and call it done.

Seafoam for the intake.

Do not use TB cleaner on the your TB,it has a special coating,use only soapy water.

Also do not use seafoam,not really a good cleaner and just makes smoke and that is about it.

+1, I am also interested in knowing about this. I have an '02 and an '11 and have used it both with no ill effects.

On electronic throttle bodies(your '02 does not have this) they use a special coating since there is no IAC and to help reduce carbon build up.That coating is very easily washed off by harsh chemical cleaners.

The Chrysler's with the 5.7 HEMI's have it the worst since it will actually set codes that can not be erased till the TB is replaced.

What an IAC?

and also

This coating did not help at all to keep carbon from building up. So I don't really care if it's gone. I'll just use TB cleaner every 10k miles. Not like its a difficult job
