So my hardly used 2016 1000 has an idling issue. I have changed injector wires and put fresh gas in it. I only use premium non ethanol in it and was still not idling so today put in new spark plugs in and cleaned off air control valve. Now putting it back together so hoping it idles better now. Plugs didn’t look that good. It only gets short runs around our neighborhood and have read that it could foul plugs. Am having a hard time installing the piece of metal that goes on drivers side of intake on plastic piece that is behind back of seat cannot figure out what the purpose of that piece is for and is it necessary to have it on. ? Hoping someone can have some I put on this.
