Otherwise, could be any number of things.

im sorry if the question is stupid but..what is INPA, is it like the jb4 interface? and when you say stuck around 5000, is that at idle or when running?

and will this sensor cause any performance issues? and i would assume the misfire on cyl4 could be either an injector or coil since the spark plugs were already changed?

thanks for the help
