Anybody else notice a slight misfire on their ecoboosts in sixth gear at low rpm? If I am going say 50mph and slightly step on the gas to accelerate i can feel it jerking back and forth like a misfire. If you step on it so it down shifts it works perfect. I have also noticed as of late that if i'm idling at a light it will once in a while feel like it misfires also. Wondering if it could be a coil problem as I read on another forum that there has been a couple issues. Truck is booked to go into dealership on the 23 so i guess i'll see what they come up with. Truck currently has 14000 miles on it.

 

I have the 5.0 and it seems to do the same thing. It might be a tranny issue. I have not taken it in yet because the dealer will say its me and nothing is wrong or they'll say they drove one just like it off the lot and it does the same thing. My dealer sucks.
