you have a triton 4.6 find out which cylinder is missing take the coil off take out the spring spray it with wd40 and put it in up side down and put the coil and the boot back on and your problem will be solved i know this for a fact my dad has a 99 5.4 and we had the same problem my boy at the dealership told me what to do and it worked

even though you did the the hole code thing it still misses because all you did is over ride the computer with a pop code eventually it will uncode and get worse
