I mean the wires, cylinders 1 and 3 on the drivers side are really easy to switch.

 

found out that it was cylinder 4 and 6 switched and i forgot to hook up the bank 2 camshaft position sensor when reinstalling the harness.. so now its running better but i threw 2 new codes! the knock sensor, which i literally just replaced (wtf??), and p0507, which is like the idle rpm sensor. ive read that clogged cats can possibly cause that code which would make sense because my cats exploded haha but its either that or a vacuum leak or the tb.. which i cleaned while having everything apart. any idea which of these options would make the most sense?
