Misfire cyl 1,3,4,5,6, and random
so I just did a head gasket kit on my 2003 TL Base @278k, before the head gasket fix I got the car for 400 bucks because the gasket issue and random misfire. After rebuilding it runs a lot better but had a cyl misfire on 5. I tried swapping two coils around and that gave me a misfire on all cyl. except #2 plus random. the plugs are new and gapped to spec, NGK (NKG?) double platinum, but the coils are not new. I have Checked for pinched wires or anything I may have left unplugged, but im running out of ideas at this point. Any suggestions?

Welcome to AZine.
How do you know there's a misfire on all cylinders except 2? If you're going by OBD2 codes, they don't mean anything. Also, you shouldn't have gapped any spark plugs. They come pre-gapped if you bought the right ones.
If swapping coil positions affected the misfire, then the coils are the problem.
