so after swapping plugs and than injectors I'm no longer getting any misfire codes still kinda feeling like it at high rpms but its difficult to tell between a misfire and backfire with unrestricted exhaust

while swapping injectors I noticed my rear middle injector had what seemed like a disconnected harness possibly from header installation while moving wires to disconnect fuel rail.

Could a lack of fire in that cylinder cause the front cylinder 3 to misfire or shoot me a misfire code for it?

now that my problem has apparently fixed itself should I be concerned.....
