Default Cylinder 2 misfire

Just bought a 2002 dodge ram 1500 3.7L V6 magnum has a misfire on cylinder 2 sounds almost like an exhust leak
Symptoms are
fuel build up on cylinder 2 spark plug
carbon build up on same spark plug when i bought it but replaced it
smokes very bad
loss power
rough start
idles ok
rough at about 1500 RPM
idles at 500-700 Rpm

Steps taken to fix
Changed coil to different cylinder
replaced coil
changed fuel injector to different cylinder
replace all spark plugs
changed Catalytic converter

problem still is there what else can cause a misfire and bad smoking?
