Searched the forums and did not find anything related (Maybe I missed it ) but has anyone found the need and or tried to clean the inside of the 4.2L air box / resonator? (The box with the Vortec logo on it) Just curious ....

I think I did once on my 02 because it was full of oil from the vent, which is why our throttle bodies get so crudded up. I think I used a can of brake cleaner, swished it around and drained it. Not much else you can do.
