hi everybody.

Recently, when I drive my car, I have a kind of hissing on my gas pedal. This noise is not permanence but intermitance I think. I found a video of the sounds that my PDAL is on Youtube but it is much less pronounced on my car.


If anyone have solution.

sounds like a leak in the vacuum brake booster

whistling like that of the video but really less strong. I do not have air noise in the pedal I have the hissing sound. We can comnparer whistling with siflement ears.
I have this noise only when I press the acceleration pedal. The sound decreases when I loose the gas pedal but it is not as permanant sounds.

you will have to stick your head under the passenger side dash area and remove any covers. there is vacuum there for the hvac controller and stuff, if its that you will hear it better. if you hear it more under the hood must be a vacuum leak there. there is no actual vacuum involved with the gas petal. but it sounds like a vacuum leak of some sort

okay i will looking for tomorrow
