Default Small hiss from throttle body area???? vacuum leak? any one else...
I can hear a small hiss coming from the throttle body area. 95% sure its vacuum leak, but i cant seem to locate it. Has anyone else diagnosed a vacuum leak in that area? thanks.

Well for beginners you might need to do this soon. From there on you can check this to see if you have a boost leak. Hope this helps, good luck.

Sorry I didn't specify I have the 3.0 liter. I saw a post once and the guy had the exact same problem with a hissing sound. He made a YouTube video too. I can't seem to find it. Thanks again.
