good day everyone. I own a 1996 XJ6 and when I am driving espically at low speeds I have a buzzing noise coming from the front end, its not that loud but I hear it it a lot of cars I drove in, and now I hear it in mines. It has nothing to do with acceleration, I just hear the buzzing even when I let my foot off the gas pedal, and then as I go to brake, the buzzing starts to diminish until I get to a complete stop. Anyone know? Maybe a noisy air pump, air filter?? Anyone please, thanks!
