Stressing out about this code. Once the engine light came on I never noticed really a decline in performance but I wasn’t going fast or anything. Just cruising. Once I did some research I noticed It could be the o2 sensor. Ordered one from Amazon and installed it but still no change. Light is on and that’s when I notice the bike starts and idles fine but mid to high throttle it’s real sluggish and non responsive. Just orders a Polaris o2 sensor and it’ll be in in a few days. In the meantime I Checked the fuel pump and ran a pressure test on it and was getting 59 psi while idling and while in neutral I gave it some throttle pretty good and never saw a decline. Pulled the arrestor off and cleaned it. Clean fuel filter. I did not ohm or know how to test the fuel injectors. Anyone have these problems? My ranger is a base model 1000 sohc.
