I have a well maintained 1987 760 turbo wagon. Wiring harnesses have been replaced and it always runs well and has been recently tuned. Last week some unusual things began happening. To start with the rear wiper would just come on for one swipe every few moments ? The car also started hesitating occasionally, sometimes at the same time as the wiper ? When I was at a traffic light it missed and stalled, it never stalls. It started right up and ran ok, but this is strange. I was thinking of checking the grounds ? I have had issues with grounds before. Once the headlight chassis ground was bad and all the headlights came on but were dim. Just looking for some advice and answers. Thanks for the help. I will let you know what I find. Hopefully I won't get stuck.
