Shaking at Idle
It's a 1991 560SEL and I have a bit of engine shaking/bucking when at idle after starting. After warm-up it is less pronounced, but you can still tell there is slight shaking at stop lights. Mileage is less than 80,000.
The spark plugs have already been changed. I'm thinking of changing the distributer cap, rotor and spark plug wires. Do you guys think this will help?
Also, any thought on changing the ignition coil?
Thanks in advance.

Take the cap off.. very common on the old v8 motors. When you take of the cap the contacts will probably have a bunch of corrosion!!! the coils dont go bad that often start with the cap,rotor and wires. Also check for vacumm leaks , the intake gaskets and all the rubbers under the manifold .
