Between 5000 and 7000 rpms the sled is starting to misfire as I feather the throttle up and won't go away unless I hit it wide open and let off the gas and continue. It runs fine then. It does not always do this but has been happening more the last 500 miles. I run fuel med all the time with premium. Sled has 2000 miles on it. Could it be a bad plug or coil that goes above a spark plug? Any advice is greatly appreciated. Thanks
