I've began noticing about 2 - 3 months ago that while coasting up to 50-55 mph my truck begins to hesitate with a slight banging when it occurs. At first I was worried it may have been transmission, but once I talked to ford mechanics, they reassured me it was not, especially at 85,000 miles. I then noticed that taking it out of overdrive prevents the problem. It doesnt act up unless Im on the highway bw 50 and 60 mph. It seems to progressively get a little worse and occasionally I can feel a jolt, as if it'sstruggling to shift into OD. Any ideas on what the problem could be, I'm really hoping it isnt much, just paid the darn thing off!

 

time for a tune up?

 

Time for plugs......I am sure that the electrode on several of them is missing the loop that creates the gap for the spark......my '06 SCREW FX4 did the same thing around that mileage....

 

Check out my earlier thread. It sounds just like what you are experiencing. I would say check your plugs and COP.
