How to diagnose Polaris UTV XP1000,XPT Turbo misfire codes 65590,65591,65592

How to diagnose Polaris UTV misfire codes 65590,65591,65592 includes a proper sequence instead of just throwing parts at it to fix this common problem.
Polaris side x side misfire codes can be set because of several reasons, and if you're like me I would rather do some diagnosing first than throw hundreds of dollars at it hoping something solves the problem.
If you follow all these instruction you will know whether it is time to get your valves adjusted, or even if your current tune is causing this issue but I want to know my engine and clutch is sound before changing your tune because it could be a bandaid fix that is covering up something potentially very costly.

My 900 is actually misfiring at throwing codes. Has fresh top end. And new head and Valves. Ran good for maybe 30 miles. Now runs terrible and spitting sputtering and popping. Has new fuel pump too. I’m lost!!! Maybe jumped a tooth I just don’t know. Thanks

Thank you for this video. I've had my 2017 xp4 turbo for last 2 years and just recently on my last 2 trips I've gotten codes 35590 and 35991 my machine pops these codes after about hr of running the machine hard and I loose all power. I turn off machine wait a min and turn it back on and I have power again then drive about a mile and codes go away then about another hr or 2 I'll be fine before I repeat process. This is never happened to me until this year and was after I did my maintenance on it. Changed all fluids in machine new brakes new plugs cleaned out belt and clutch new s n b air filter. I do have an s n b air filter separator kit on machine and a blow hole for belt with a scoop going into the frogskin. I don't have the equipment u have but where do u think I should start?
