Its 30-is years old. Make an offer. This item is used, however its fully refurbished with a new iac valve and tps. That said, this was fully functional when I took it off.
I like money more than stuff cluttering up my workspace. I had just replaced the idle air control valve and throttle position sensor too. It also comes with two new injectors - boxed and the that are installed verified to work. A pair of brand new injectors are also included in this offer.
This thing came off of a 454, but for my situation I required bit more than this could provide.
