Vibrating sound from filler cap area
Standing next to the car while the engine was running I heard a noise suddenly appearing from the tank fill area. It lasted for some time and suddenly stopped. When it started the next time I opened the filler cap and the noise stopped. This probably has something to do with suction control of the vapor from the tank? Filler cap or some other valve clogged?
