no. it makes the sound when it is parked with the engine off. it can just be sitting in the garage and the noise will start, last about 2 or 3 seconds and stop. it will do this more than once with pauses of anywhere from 5 minutes to 20 minutes to an hour, and then somtimes it will not do it at all. it sounds as if there is a release of built up pressure blowing off from somewhere around the muffler, cat, or fuel tank area. thanks for your quick reply. hope you have some more ideas.
