1986 Mercedes-Benz 300E 3.0L Poor Idle Quality, Hesitation, Stall, Hard Start
This car has a very slow and poor idle when cold. It does
have a vacuum leak at the #5 injector, but idle quality and
speed do not improve with a shot of carb spray. Once the
engine warms idle quality and speed are good and the
hesitation goes away.
