2003 Yukon won’t accelerate past 3,000rpm and chokes/sputters

[edward case]

Intake gasket leak equals unmetered air.alsi make sure your intake plastics are in place tight with no cracks .

Last week, my 2021 GMC Yukon w/40k miles began sputtering/jerking at slow acceleration into higher gears. I never changed the spark plugs. However, there are no check engine lights illuminated on the dashboard. I hooked up an OBD scanner, and of course, since no error messages were illuminated, the scanner check revealed that the vehicle was normal. I've used 87 octane for the majority of the time.

***Any recommendations on the possible issue?

This is the 2000-2006 section. You’d have better luck posting in the 2021+ section of the forum.

Got it, thanks.
