I had a 205 f 150 4.6 and now I have a 2004 f 150 4.6 . both trucks did this vibration in engine . they only did it rarely. the only way I could stop it was to pull off road, shut engine off and wait a bit then restart and be on my way and the vibration was gone. does anyone have an idea what is causing this., before I go to dealership and lay out the loot. p.s. the mileage was 17,432 on the 2005 and is 36700 on the 2004. thanks
