- mod 08 nytro, 2-2007 phazers and a 2010 sno pro 500 speedwerx exterminator. new 2014 nytro for towing the snowcoach. 2015 Viper mpi turbo
my 2015 viper ran great all season but now I went to move it and it started hard and sounds like its running on 2 cylinders, I replaced all 3 plugs with new ngk cr9e plugs, still did it, I replaced 3 ignition coils with 3 good ones still does it. What should I try next? I charged the battery too and still does it. Any help would be great Thanks

Maybe an injector is not firing or clogged ?
