I just installed a JB3 and bought 10 gallons of 110 octane race fuel to mix in tank. THIS seems to lower the chance of misfire under load for some reason...only had one limp mode recently and the CES light went off after one night...Any help or recommendations would be greatly appreciated.
Thanks
Have you followed the guidelines on the first page and video? You should really replace all coils and all plugs at the same time.
