Hissing sound from under the car...
Can anyone help me figure out what a hissing sound from the bottom of the car could be? I haven't been able to pinpoint the exact location of the sound but it looks to be isolated in the rear of the car. Can't quite seem to locate it though. Does anyone know what this sound might be? I first heard it after turning my car on (after 2-3 days of sitting) and I was walking around the car to check my tire pressures while the car warmed up alittle and I heard a funny hissing sound from the bottom of the car. If you can help me diagnose what this is, I'd really appreciate it! Thanks in advance for your help.

I just started noticing it now. I have two trouble codes that I have yet to fix. One of them is the 0510 (rear o2 sensor) and the other is the 0302 (excessive or insufficient EGR flow). I doubt that any of these trouble codes have anything to do with the hissing but I could wrong. Any thoughts?
