I have a 1995 mercedes benz s420 with a couple of gremlins. Probably the biggest problem I have had with the car is the ASR switching on when I am at a high RPM or at high speeds. The sensors have been replaced and that didnt fix anything. It used to only happen about once a month but now it can happen 3 or 4 times when im driving on the highway. I am at a loss here. What do I do?
