Everytime i step on the accelerator im getting this weird humming noise from my engine like air is blowing through a tube but has a leak or something. I checked to see if the air filter was intalled properly and it was any other ideas?

 

Do you have a Cold Air Intake?
Also, are you 100% sure its coming from the engine?

 

NO CAI and im pretty sure it is i cant really tell though, when i park and rev the engine i get nothing only when im driving then i hear it if that helps
