2002 Lightning Misfire won’t go away

Check the wire pigtails, should read voltage on one side.
Ever had the injectors cleaned?

No codes come up? Could be the injectors but sounds electrical.

What catch can is that ?

Yea I checked them out and still running bad checked with multi meter, also checked for vaccum leaks and everything looked good. Any other things that could be causing this problem

Wonder if they got the timing chains installed correctly, who did the head work?

My first thought is bad piston. Have you checked to make sure you don't have a bad hole?

If you have a egr delete it has to have a tune or it would light up

Connectors for coil packs not being fully seated and clipped or retaining clip broken (common). tip: squirt a little brake clean inside of connector before connecting it to coil pack, it makes the silicone weatherproof seal really slippery and she slides right in. Tip2: if broken, use a little silicone where retaining clip used to be and connect to coil pack. That will keep it plugged in and still allow you to unplug until you replace pigtail connector for coil pack.

Rich bank 2 and you claim cylinders 5 and 7 are misfiring, which are both on bank 2 (drivers side); sounds like cylinder 5 and 7 fuel injectors are stuck open possibly

Most likely camshaft timing is off. Compression test will tell you what you need to know.
