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

    Hey all, I’m having an issue on my 2003 Yukon that seems to be fuel related. The truck had all the seals redone in the motor not too long ago, holds great oil pressure and runs smooth, but I’m unable to accelerate past maybe 1/4 throttle.
