Post blizzard here, my power-steering went, fluid leaked right out of reservoir, brought to certified mechanic and he said I lost a hose/clip n he replaced it. When I drove out of there it was still pretty cold out, my idle revved higher than usual, but when I slow to stop @ red lights my car feels like its going to stall n idle is low. The car has a vibration that seems to shake motor erractically, makes me feel nauseous driving it n exhaust is loud....and smells different...strong fumes...no smoke though. Battery light keeps coming on then goes off, Serpentine belt is still intact and aligned. I would appreciate anyone's knowledge/feedback/help. Thank You-NYGirl who loves her old Mercedes baby.

 

You have a W163 generation ML, so you'll probably get more info in that forum.
