My 2001 F-150 super crew 5.4L starts sputtering when I am trying to accelerate slightly while driving at 40-50 mph and around 1000 to 1500rpm. It feels like fuel starvation but it smooths out if I give it more gas or let up on the acceleration. I think this is the area where the computer is trying to decide whether the transmission needs to shift.
Any ideas? Thanks
