Code 13 help
So I just bought a 2009 kfx 450r. Finally got to ride a bit this weekend and after about 5 mins when I went wot it would cut out and fall on its face the far left light came on. I checked the code and it came back a 13. It has cams, crank, athena head and high comp piston. The air box is open. It came with a tuner but isn't installed. I did find a connection by the air box that isn't t connected. My question is where is the intake air temp sensor and if the air box lid is gone will that make it throw the code?
