cylinders 2 4 & 6 are the only cylinders misfiring. The other code that pops up has to do with the o2 sensor. Also noticed the old plugs were burning a little hot. What's the problem? What makes only that side start misfiring? Is it the cat and o2 sensor problem? Or the coils?
I just changed all six plugs in my truck. now have a misfire in cylinders 2 4 6 on 2002 Dodge Ram 1500
Sounds as if you either bump 3 plugs installing and closed the gap OR you've crossed the wires if you didn't remove one at a time. Good luck.
