(1990 Mercedes-Benz 300SE)
in Oxford, NC on January 09, 2018
the car idles fine in park, when put in drive it skips, have changed spark plugs, new disturber cap and rotor, new spark plugs wires, have cleaned the idle control valve, and checked houses for wear and tear, all is fine. It just idles like it wants to cut off when in drive and reverse.About 6 months ago I put new fuel pump, and filter on and car has was fine, it was when after I replaced the distributor cap, rotor, spark plugs, spark plugs wires about a month ago when all the problems started.

These older Mercedes have a unique central fuel distribution pump. Its an early mechanical fuel injection system. They can need adjustment or replacement from time to time. You will definitely need a Mercedes specialist with this.They will hook up a lambda gauge to set the unit properly.
