Trouble code 5 on 1993 300e 2.8
The check engine light on my 1993 300e 2.8 has been coming on lately. I have checked it by depressing the button in the box and come up with 5 blinks over and over. When I reset it the light stays off for varying amounts of time from minutes to days and then comes on always code 5. Does anyone know what that code indicates on my year and model?
