My car hisses near the rear section(near the wheels I think). I don't know if it is an exhaust leak because my tachometer is stable when idling. What could be wrong? Thanks guys

 

Could be your fuel pump. I took the back seats out of my car and when i took the seats out and i started the car up there was a hissing sound, but i think its the fuel pump. Im not sure where the fuel pump is on this car so im not positive, but if its back by the tank then i bet its that.

 

Sounds like you ran over a Snake and it got caught by the rear wheel well

 

I think it is the fuel pump. Mine does it too... right near the rear right wheel. It seem to cycle on and off.... on for like 2 or 3 seconds, off for a second, and then back on. It's probably a pressure release from the high pressure line of the fuel pump assembly or something of that sort.

 

definitely fuel pump......no worries.

Thanks guys. It's you guys that make this forum great
Wonder why I didn't notice the hissing before coming back from a 1 month vacation.
