e420 drivabilty problems!!!
I just had my 94 e420 (Great Car!) in for the 90000mi maint. no real problems found but I have recently had a couple of instances of the car stalling, or idle speed dropping. It has happened just a few times. I have seen it once and my wife a few times. Never a check engine light, but do have an abs light from time to time. From reading DYI article on evaluating the electronic engine controls it seems that I may have the same problem discussed Ie a bad over-voltage protection relay. Can someone tell me how to find this relay on my car? Is it a dealer item? Price? Would it be worth a try in my case?
