07 Wake 155HP Throttle Issue???

[mark_45040]

Never had any issues with the ski. The other night, the ski would not start or stay running once started unless you held the throttle in slightly. I was able to run for an hour or so without any indication of power problems other than stalling out if I did not hold the throttle in a bit. No warning messages were being reported. I thought it may be related to the battery, but not so. Took it to service center, and the computer did not show any issues. Only thing odd was at full throttle the computer only showed 80%. They reset the throttle via the software program, but it did not impact anything. Put new plugs in, and that did not do anything. Has anyone else experienced a similar problem? Any recommendations on how to diagnose and fix?

thanks

The Fix

Only a few things will cause no idle and not show a fault on the computer. Throttle cable with no play and a bad idle bypass valve. In my case, it was a bad idle bypass valve. Reset TPS and everything is fine. First time dealer has seen this issue. Hope this helps someone who might on day experience the same issue.
