Hi John, Did you ever solve this problem? I have the exact same issue with my 2005. 23,000 miles. gave me a P358 code (failed
coil on #8). I went to Ford and paid $80 for one
coil. Still does the same thing. Put a noid light on the injector wire and it shows that the computer is sending pulses to the injector so no fuel issue there.. If I use manual on the trans and shift it the miss isn't noticeable until 5th gear. At like 35-40 mph and above. Any extra throttle shakes and misses... very annoying.If I downshift it and punch the throttle, it is not noticeable. I replaced the computer two years ago and am wondering if the computer is the issue. Thanks, Dennis
