I have a 2001 lightening with 95k miles on it. just started getting a slight rough running condition. just enough to feel in your seat or foot feed. it happens when excellerating and can feel it when when idleing down. treid replacing spark plugs but still there. I did notice when changing plugs... that the right bank seemed to be more wet on plugs than left bank. left bank looked normal white burn on plugs. No DTC codes. i replaced one of the coils on right side but still same thing. just wondering what/why right complete right side would be more wet (on plugs) than left side
