It came on a used motor I bought out of Massachusetts. A mistake that sped up the process of me selling the buick just about five years ago.
I will say that I've missed this site. This thread has been fun. Thanks, guys.
Includes TB, plenum, TPS sensor and IAC motor (everything pictured). I'm not sure how good the plenum works. It may be more of a coffee table conversation piece than a useful Buick part, you decide. $65 shipped lower 48, paypal preferred.
I'm cleaning out the garage. These two items have a few minor scuffs from sitting around for 10 years, but they are still in great condition and have never been installed. $32 takes the pair shipped anywhere in the lower 48 states. Paypal preferred.
