anyone know what it might be, this never happened before, its aloud humming noise and if you touch the p/s pump you could feel the vibration, and when steering/turning its gets louder, i took it to the dealer but they said it was the alternator :bs: so they sold me a battery(pissed) so i almost got in a fight with the tech. mngr. and then he told me its suppose to be like that when in fact i never heard that noise before i think it might be the bearing, and my driver shaft is messed up it makes a loud clacking noise, and for damn sure my engine is knocking cuz it had a missfire, and when i idleing it revs its self i see the rpm needle just going up and down i think it might be the idler control valve, but they said that one of the plugs had a crack on the ceramic, supposably they changed it but its still doing this................as you can tell I NEED HELP!!!!
