I've had my 03 V8 since March and its always had this weird situation where it makes this air hissing sound. You can hear the sound build up from a very minimal sound to this whoosh and then it goes away. It does this every 30 seconds to a minute. I dont hear it as much when the radio is on but its still noticeable. It is extremely annoying when the radio is off.
I tried doing a self test but no codes. I am assuming its a leak in a line but it sounds like a valve or something within the system is allowing the pressure build up and then it blows off and restarts.
Anyone else have this problem?
