I have a 2007 F-150 5.4 auto 4X4. My issue is when I start up a hill it chugs and bucks. It doesn't do it all the time. There isn't trouble lights on the dash. Torgue convertor or throttle switch?
I was about to suggest checking your plugs. I had my truck do the same thing one time and I was sure my transmission was gone. Then I opened the hood and saw the arc coming from a plug wire. Sent from my iPhone4 using Tapatalk
