Ive looked around maybe someone can help or enlighten me, since the dealer cant. Ive got a 2012 f150 5.0 5,000miles. Sometimes when i back up out of parking spot or driveway and shift to drive start taking off light acceleration the rpms jump from 1000 to 3000 and the truck really "bucks" seems like its 2nd gear usually happens. Again it only happens in parking lot situations or <20mph

Mine did that in 1st gear. They had it at the dealer for a week. They said it was a bad program and bad cam shaft sensor.

Dealer couldnt find anything last time i was in. May need to take it back

Mine does the same thing, I have a 2012 5.0 as well. It seems like it happens if I don't let the truck warm up for a minute or two. I didn't notice it until the weather got cold. Like I said, it's only of I try to take off and the truck is cold. I know it shouldn't be like that but it is what it is.

If I drive my truck with a cold engine, I experience a mild shake. Now, I watched PBR last night from Anaheim....now that's bucking.

Lol true that is!! Mine seems to happen warm or cold. "It is what it is" works but not when you spend big cash on a new truck
