My 2004 F-150 was misfiring on cylinder 3, so I took it to Jacky Jones in Cleveland Ga. for them to diagnose the problem. They kept the truck for about a week just to tell me they needed $675 just to take valve cover of to look at valve train, this is on top of diagnostic fee. I refused and told them I would pick the truck up first thing the next morning. I get there to pick my truck up, pay the $125 diagnostic fee, and head out. Don t make it a mile before the whole truck begins to shake and cut out, running 100 times worse then when I took it to them. Come to find out they didn t have any of the coil packs plugged in. My 16 year old son fixed a problem a so called Ford service tech. had caused. What a shame. I recommend taking your vehicle to a different service center.....Perhaps Greene Ford in Gainesville Ga.
