my brother bought a brand new 06 m7. I took it for a rip and immiediatly reallized the engine was missing at high rpm, we assummed it was an alttitude problem becouse we were riding in the praire. Well my bro was heading to the mountains so he hoped higher altitude would solve problem .Well no luck still missed at high rpm it seems like electrical. Changed plugs no differece, the sled is currently at the dealer and they are scratching thier heads. It has been 2 weeks and they have not found the problem.Has anyone experianced this phenomenon. The only mod was and after market can.
