I was wondering if you would check a couple of numbers for me. After searching and finding your old posts about TBI numbers, I saw that mine wasn't listed in your list. I have a TBI casting # off of my Turbo City 454 unit that I would like to know the year and vehicle it actually was intended for, if possible. The number is 17112562 on the right front, and also has M2967 there also. On top of the TBI by "Rochester", it says 86302X.

Also, what #AC Delco, IAC motor should this unit have? The one in it is a 17113099. Is this right? It has always taken a long time to drop down to an idle when braking, and when it is at zero counts (after resetting), the pintle is obviously not shut. Shouldn't it be?

Thanks in advance.

any iac for a 454 should work. but... as for you tbi. its probably a cataloged number. which means the dealer uses the most recent 454 casting number. so i probably couldnt get it.
