Sorry for the delayed update.

It seems to run fine, just that "shudder" at idle. No codes are being thrown.

Plugs and wires changed as stated. I replaced the plugs with original champions (from NAPA), and MOPAR wires from the dealership.

It did not run any better or worse after the swap. I noticed it fired quicker with the new plugs, not as much cranking.

I'll have to check my coil pack too, and I still have to check the resistance on my injectors.
