I had similar problem.
Cyl #:X (cant remember exact one, lets say it was CYL 1)
Code was CYL 1 Misfire.
First thing i did was replace all plugs (needed to do it anyway)
Went away for a day, then came back. Car was shuddering.
Still Cyl 1 misfire.
So i know it wasnt plugs, next was to try coils.
Instead of replacing all coils, i move the Cyl 1 coil to cyl 2 and vis versa.
The fault followed and now i had fault in Cyl 2.
Bingo, coil pack.
Fixed!
