    I have a 96 tacoma 4x4 v6 and it has a buzz comming from the 4x4 vacum housing near the break booster. It only seems to buzz when i am done driving, and it is loud. Sounds almost like a bee is trying to get out of there, but it is a synchronized sound(buzzing every 5 or so secconds). Anyone know what this is and if I can fix it. thanks

    we used to have a saying when i worked in the service department to explain problems like this. TMDT. This Model Does That. not very comforting i know, but it isnt going to cause any drivability issues or anything, just bug you.
