Thanks for the heads up will. I was planning on cleaning my throttle body when/if i install a rice pipe this spring or summer. I'm gonna have to go find one this week. Nothing sux more than waiting for the last part you ordered to come in for 2 weeks because it'* hard to find or can't be found at all!
i'm usually able to stop myself from being stupid....but i'm gonna fail here.
I would say that'* it'* shocking to see GM make such an odd call on a part like this, but i know better. I have gone to the parts department of the local dealership (which is now closed) a few times and have seen brand new 3800 engine blocks in there black plastic container on a pallet waiting to be installed to replace destroyed blocks from failed UIM/LIM. And worse....at the owners expense.
But i guess it'* more of a corporation thing. it hard for inanimate objects to "feel" for example guilt. :P
