I'm getting a loud air leak coming and going from the airbox. When idling I can make the noise happen @around 2000rpm and if I open the airbox the noise goes away. I have no engine lite. If I take the air filter out n close the airbox I get no noise. I would appreciate a response. Thank you.

Hearing a vacuum from the air box is normal. Fuel and air are drawn into the engine through there. Is the engine running properly?
