| Description of the problem | After about 28,000-30,000 the truck would severely buck/jerk/hop when towing a load. The problem occurs in third gear most commonly. Upon acceleration up a hill, the truck has an extreme buck. The rpms raise and lower up to 400 rpm. Ford has determined this action to be normal. The only way i have fond to stop this, is to let all the way off the accelerator, and then try again. The truck will then start this again, in which i have to let off. On a safety concern, this occurs on most entrance ramps to interstates, which makes for a hazardous condition trying to merge into traffic, because basically ford is telling me not to try to accelerate past second gear until i am no longer headed uphill. Fords first suggestion was the trailer type, which had no effect (tsb 07-6-09), which only concerned gooseneck trailers. The truck also does this action with a bumper pull trailer. I have taken the truck in 11 times since july 2007, and the service men tell me they can feel it, there is a problem, but no one knows what it is. Ford then came to the result this was normal for that truck. At 8000 miles, the truck had a bad injector, after replacing this, the dealership "updated the computer." since that time the truck has not had as much power as when i purchased it. The serviceman told me sometimes these updates will change the output of the truck, or decrease the power. The truck now has a leak in the rearend, which i believe to be a result of the bucking and jerking ford is calling normal. |
