Customer: Issue with #6 (code P0356) on a 2006 Ford Exp with 5.4L v3 Triton. I replaced all spark plugs with Ford Plugs, and bought new coil packs. Now the car runs like crap and the code above is thrown.

Customer: 2004 f150 5.4 p0351 and p0356 we have changed coils plugs wiring harness and pcm . still getting intermitant code . when starts missing around 50 mpi heavy accelaration clears it up for a few miles then codes all over again. used snap on computer to scope finds nothing.

Customer: OBD codes P0351 thru P0356 - 2004 Ford Taurus, 6cyl, 24v car has intermitent hesitation while traveling 65-70 miles per hr and has almost stalled twice at stoplight. Starts fine and runs fine, just intermitent trouble with check engine light on for 6 days.

Towed home and found P0355 P0356, with P0353 pending. Replaced all 6 sparkplugs and ignition coil 5 & 6 with battery disconnected to clear codes. Started, still running very rough and almost died once.

i am reading a code P0356 from my scanner, and the problem is defined as ignition coil f primary/secondary circuit Ford Mechanic: Ron The code 0356 would indicate a problem with the cylinder #6 coil and or the connector .
