Hi I recently bought a 500 sportsman and the first ride I went not far and after a few minutes the machine started backfiring and trying to stall. Took it to my shop and see the engine light is on. I researched and came with codes 22 and 47. I adjusted the throttle cable and the sensor seems...

My sportsman started sputtering and engine light comes on and off when throttling. Drove around block and startled sputtering and the orange engine light will come on and off . Sporadic sputter and light. Oil was a little foamy about 1800 miles on machine. Any ideas or what to check?
