I have a '93 GMC van with the type W V6. On the top left side of the
engine (looking from under the hood back), is a peice of linkage that
goes from the throttle lever to a rubber bellows on the top left side
of the engine. I suspect its some sort of damper, but am not sure. The
metal bracket on the back of the belows , that holds to linkage is
broken, so it is no longer conected to the throttle lever.
My questions are: first what is the bellows, and what does does it do.
Second, can I drive it without it? Is it possible to just replace the
bellows? Finally is there an easy way to get it out of there?
