Get a compression check done. Just to be on the safe side.

Re: Cylinder misfire any help?
spark plugs AND AND AND wires.
Everybody always seems to buy JUST plugs and then they wonder while they still have a misfire. Use only autolite or motorcraft plugs. If you use autolites then get the regular kind, not that double plat crap or you will have a misfire still. That should fix your problem.

New plugs wires coil, egr valve, cleaned IACV, checked for vacuum leaks, sea foam in the vacuum lines. It all started with a trip through the car wash

Re: Cylinder misfire any help?
115 psi should be plenty of compression to get fire. Have you swapped the wires between two plugs, just to be sure it's not a bad wire?
