Air being drawn in around elephant trunk. Or Idle Speed Control Valve? Check idle speed stabilisation unit behind off side rear light.
Make certain trunk is properly connect to AFM. Best way is to release airbox from sidewall clip. Then tigthen jubilee clip holding boot to AFM. Then reclip box back in place.
