Brand New Workhorse Throttle Body Assembly with Throttle Actuator for 2003+ model year 8.1L Engines in Workhorse Chassis.

Applications:

All Workhorse Chassis 2003+ model year with an 8.1L Engine

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. ( Support )

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. ( Support )

what is the correct throttle body for this rv. I have a throttle postion that under load teneds to flutter. not like a miss.. idel often rev a bit up and down. suspecting bad/dirty TB since it seems to run fine at most rpm ranges. .. should I replace the TAC at the same time? ( douglas G sylliaasen, 11/07/2021 )

Yes, this is the correct throttle body for your VIN. I would have the engine data analyzed to find out if the commanded and actual throttle position are matching before replacing those components. You do not need to replace the TAC module at the same time, usually you will get a check engine light and DTC for an issue with the TAC. ( Support )
