1992 190E sportline, 1993 300ce, 1993 300ce sportline, 1992 300sl
Just noticed after some work at my indie that my mpg gauge is swinging across the dial up and down, and very slow to return to 0 - used to be very controlled and was always the same. What and where is the trigger for this from the EZL? I have also noticed that the shift point from 4th to 5th ( this is a 1992 300sl with an auto with electric 5th gear) is about 5 mph higher than it used to be. seems to be an electrical issue, possibly an ovp going bad?
