I have a misfire code for #4 cylinder on 2008 escape 3.0L. I have done the following so far:
replaced spark plugs
replaced coil pack
Swapped fuel injector
Checked injector resistance (13.1)
checked cylinder pressure (120 psi)
also pulled spark plug out, taped it to coil and have good spark.

anything else I can look at?

 

Yes what does the spark plug look like for that cylinder? Is it wet, dry ?
If wet , could be the coil is not being energized, If dry , could be the injector is not being energized . Those are two checks you might consider, let us know what you find, thanks.
