P0316 code
My 2007 with the 5.4L has been shuddering several times in the past week. Sunday it was like I was driving on the rumble strip, the truck was shuddering horribly but no codes. Yesterday it began shuddering once again and the check engine light flashed and I was able to pull the P03016 code for misfire below 1k rpm on start up from my edge programmer. I was driving around 1.5-2k rpm when the shuddering was at it's worst and I haven't gotten a code for a specific bank yet.
Some additional details : The truck has 84k miles on it and had new Motorcraft OEM plugs installed by a Ford dealership at about 64k miles and starts flawlessly so I'm not suspecting a coil pack. I have heard that sometimes when the temperatures frequently shift and gas stations begin switching from winter blend can cause these issues. Any truth to this? Should I try some fuel injector cleaner before taking it to the shop to see if that helps?

5.4l doesn't have plug wires.

It ended up throwing a code for a #7 misfire, seemed to happen during rainfall. The 1st time my truck began shuddering was after a trip to the car wash with an under body rinse, seemed to occur during the rain as well. Ruled out the injector and changed the COP, has been running fine for several days.

Have you checked out your fpdm? Underbody flushes will soak a bad/corroded one and cause all kinds of odd issues.
