Many things can cause your issue. A little more information may be helpful. First, is the check engine light on? Also, do you have a fuel injection tuner installed? And, have you made any recent modifications? Thanks, P.J.

No check engine, it has the commander box on it to change performance but I never used. no modification . Like I said has never gave any trouble until now also when idleing reaves up high then back down .

The first order of business is to unplug and remove the tuner. It will not harm the bike in any way to run it without it. They often cause connection issues due to having slightly different terminal sizes and adding two more connections to the system. Try this first and let me know what, if anything, changes. Thanks, P.J.
