this morning it was cold so i let the car warm up about 15, when i went to leave i turned the wheel and the rmps almost bottom out. then jump back up all the dash lights and head lights dimed out and i thought for sure it would stall. turning the wheel deffinatly made it worse and the having the heat on makes it worse too. is this an alternator problem i think it is 14v? any input greatly appreciated.thank you oh yeah i have already replaced this alternator twice. maybe there is something else going on causing power issues?!? and lately ive been hearing what i assume is the alternator through my speakers. i dont know if that is related, but there is deffinatly some kind of power issue.
