Truck accelerates fine through 1st and 2nd gear. When it gets to 3rd, it will sputter, kind of acting like its misfiring. Take my foot off the gas, hit it again and then it accelerates normally. Only does it in 3rd gear. Trans was rebuilt so I'm hoping it's not a trans issue. Any idea on causes? No codes.
The engine uses more fuel with increasing load, and the load increases when running in higher gears. If the fuel flow can't keep up with engine demands, it will stumble.
