This has been an inconsistant problem for awhile and a problem apparantly the previous owner had also. It runs great and has ton of power from the start. After riding for awhile, and doing WOT runs the ski will go into limp mode and Chk engine light comes on. In the past the code was never checked. When I had it the Code that comes up is P0353. Coil issue cyl #3. Cool the engine down, checked connections, swapped coils with the other cyclinders, still after what seems like a hot engine the code keeps popping up. The previous owner had the MPEM changed because the ski was doing the same thing. I've had the shop put it on buds and they did not find active codes. Checked the plugs at the ECM on top the motor, no moisture that I could see, but no anti corrosive lube either. I'm thinking its the ECM or maybe just spraying dieelectric grease will do it. Any thoughts. The ski runs great otherwise and it clears after pulling the laynard.
