Selling a 90mm drive-by-cable (DBC) throttle body I pulled off my truck a few weeks ago. Includes a used but working GM TPS sensor and IAC valve. I purchased this about 10 years ago, and at the time, it was supposed to be one of the best. It was pricey too, I think I paid close to $500 for it back then. I pasted a description from a Google Search.

Asking $250 OBO shipped.
