I hear things about a new throttle body and ecm having to learn each other. Is this something I can do when I replace my throttle body? ( Jeff Haltom, 03/16/2025 )

The throttle body doesn't require a relearn process or programming once installed.

Hi, when towing our Buick Envision with 2006 W-24 chassis/Winnebago Adventurer, accelerating thru 3rd gear at 50 mph, I get a flutter, especially when going uphill. Or when using cruise and downshifts to 3rd gear at 50 mph, i get the same flutter, if I feather the gas pedal (taking off cruise) i can get engine to pull load without flutter. Last year, when accelerating thru 3rd gear I experience a hesitation or flat spot at 50 mph, once over that speed everything was good, and engine runs fine at other speeds and RPM's. I have ScanGuage 3, sometimes now when this happens i get check engine light and P0102 code on the scan guage.
Is this part what is creating the problem, or could it be the Throttle Control Module? Thanks ( Gary Sieverding, 09/18/2024 )

I would suspect an issue with the mass air flow sensor, not the throttle body.

Is this the same TB as PN 1267526 with #1257080 casted on the body and 26z08x on the TPS. I also plan to replace the TAC listed here w/ last two digits 24. Just wanted to be sure that everything is compatible. Thank you ( Bill Kaufman, 06/05/2024 )

Yes, this is a direct replacement to those part #'s.
