Hey guys,

I'm just wondering I hear a hiss from the passenger side of the engine when it is at idle. I'm also getting some vibration at idle.

Was wondering if it is normal to have hissing noises coming from the engine? Can anyone tell me if they have a hissing noise in the passenger area of their engines? I'm thinking it could be a vacuum leak.

I don't have any CEL. I do want to get rid of my vibration issues though because it is starting to get annoying,

 

there will be some.
