i have a Expedition with P0305 and P1336 i canged the coil, Plug, plug wire. Still throws same code. How likely is it i got a bad coil?

I got a 17 fusion sport with the 2.7 eco boost and I got this code and for me it was a bad map sensor

Mine says po305 permanent and it clears the light out but is stored in the computer

I have a Ford Ranger 2005 with a cylinder 5 misfire. I see a small crack on the front of the coil pack... Most everything checks out good. What do you think??

I have a 4.2 2006 F150 and i have replaced the coil, the spark plug and the wire and the code remains, any ideas?

So my 97 ford 4.6 Triton has a misfire on cylinder 5. Mine doesn't have the straight line coil packs over the cylinder. They're in a quad block on the front. Can't find anything online or in the henrey book on where cylinder 5 is. Anyone have an answer?
