intermittent missing backfiring 5.4
Hey everyone, just throwing this out here to see if anyone has a clue. I got a04 f-150 lariat 4x4 5.4 3v. That has developed an intermittent miss and or backfiring during hard accelerating, also misses when getting on the highway going over 65 mph and I've noticed that it does it mostly when overdrive kicks in. I've changed the plugs, coils, recently. Any help will be greatly appreciated!

Thanks again I'll keep picking at it and post results....although the plugs and coils make it run a lot better but didn't resolve the problem....I was kind of thinking is sound like s potential vacuum leak also.....well see
