I have a 1993 MB 300E 4matic and the cruise control is not working properly. When I activate it, it does come on but is erratic and does not hold its speed it jumps and stops?? What is the problem? Can some one explain why it is doing this and how I can fix it ? Do I need a new cruise control switch, ECU relay, module or is there a vacuum hose problem or amplifier? Please help me since I am new to this car and it does not work as it should. I love this car and I just replaced the transmission and want to restore it as best I can.
Thanks, Leo
