5.4 Litre. It's been stumbling under a load, say going up a small incline at 50-60 mph. It started right after my last fill up so I thought it was some bad gas. No check engine light came on. I filled it up with fresh gas but it didn't clear up, but finally got a CEL. Put the OBD-II scan tool on it and got two codes. P0305, misfire in cylinder 5 and P0316, misfire upon start up (less than 1000 rpm).
I'm thinking it's the coil pack on cylinder #5. I'm going to pick one up at Advance Auto today and replace it.
What do you think the odds are that will fix it? Results to be posted later today.
