Hey guys and girls, I’m on a 2015 ranger 900xp. The bike has not been abused with less than a 1k. I’ve installed lights, radio and winch. Last ride, I believe I was on only one cylinder from the start. Went 2 miles stopped got fire wood and headed back it sounded like I was dragging a vine. I noticed I was down on power, stopped looked, nothing. I thought I smelled bad gas but the ranger has not started sense. Every accessory works. I hear the pump on ignition key turn. I have spark to the plugs and fuel psi at the rail. The plugs are dry when I pull them and don’t appear lean fouled. I have a 168 code but not sure why a regulator would cause open loop at the injectors. Has anybody experienced this type of problem.
