My 2001 Bonneville misfiring & running rough, it sounds like a tractor. my wanta B mechanic did a diagnostic on it, he said I needed coilpacks, so I put $85.00 coilpacks on, still runs really rough. next is plugs n wires. but I want the designer of these dang sideways motors to come n put the back 3 plugs n wires on for me.
