Can anyone help with this issue? I have changed the plug, wire, coil, and have gotten no luck.

 

Break in a wire in the harness running to the coil? Run a continuity test on the wiring? Dunno, just a thought out of the deep blue sky.

 

Here is some info on the PCM hope it helps

I got a p0354 on the CEL and I swapped coil pack four with coil pack 2, high voltage wire 4 with 6, and plug 4 with 8. code came up again 40miles later. Engine runs fine. Any common problems?

lpina650: did you figure it out? .
