Rough Idle with ABS Light On?
My 1989 190E 2.6 is hard starting and runs rough idle when engine is cold. Once the engine is warmed up the it runs fine but every now and then the ABS light will go on and the car starts to idle rough again. The battery also dies out often and doesn't seem to charge properly. I already replaced the alternator brushes 3K miles ago. Can someone please advise?
