UPDATE

So the code was not 1335 but a 1355 which is a misfire in #7 I believe. I pulled all the plugs this weekend and replaced them and still no bottom end power and rough idle. Feels like I have a MOPAR cam in the thing sitting still.

I am giving in and having towed to the indy shop to see what is up.

The number 5 plug was pretty rough and might explain the first code saying the coil was bad, but the rest of the plugs appeared to just be pretty old.

I will know more today.

Thanks for all the tips.
