vacuum leak
 

how can i fix this problem ?

Re: vacuum leak
 

Spray some engine starter fluid around your intake to see where the leak is. It will affect the idle.

Once you find the leak, tighten/replace the defective part/gasket.

What leads you to believe you have a leak?

It's an intake. It's supposed to make that noise.

it's sucking in air, and it's more noticable at higher rpm's because it's sucking in alot of air. perfectly normal.
