Dave, I have this same issue. The original code was misfire on 6 so I checked it out and it had a bad oil leak I replaced the valve cover gaskets and all the coils. a few days later I get it back with a number 1 miss with a DPFE code. I clean the tube to the DPFE and the EGR along with doing a throttle service. Ran great for 2 days. now Im getting a number 7 miss. this thig is a nightmare. had a buddy from ford take a look at it and he has no clue. Any ideas. email me @
