p0300 and p0308

I just found out its a secondary injector driver system. apparently theres two added injectors (somewhere) on the tb I suppose? it adds the needed fuel since the injectors on the rail apparently are stock #

I know I'm bombarding you guys I just switched the plug wire from 8 to 6. and now the code went from p0308 to p0300 and is idling rougher and if its in park and you rev it a little it drops back down to like 400 rpm and bogs a little. so new plugs and wires and see where it gets me?

Clear the codes and drive it. If it throws a P0306 code only then you know your issue was the wire. If you get a P0300 and/or a P0308 then you still have an issue with one or more cylinders.
