If I was a betting man, you should do a compression Test on your Engine. What you are going to find is the PTO Cylinder has a lower compression than the Cylinder on the Right. Doing a Top End Repair on your Sled will only take 4 hours to do correctly. You can do RINGS ONLY but you may want to replace the Piston if the SKIRT has marred the Cylinder Walls to ensure a longer life. It is also recommended that you make sure your Oil Injectors are not clogged and functioning correctly.

That sounds like either the throttle position sensor or exhaust temp sensor has issues. The throttle position sensor have had issues with wires breaking off. The best way to find out is to have a dealer check with their computer. If itis the throttle sensor they can adjust proper upon installation.
