My 83 500se has a slight misfire when i pull away from standstill.
It clears at about 850 RPM,also it causes the car to shake slightly when idling.
The misfire is NOT present when the engine is cold only at normal operating temp.
I have replaced dist. cap Rotor and Leads but have noticed the contacts inside the dist. cap have blackened very quickly.
Also the oil pressure fluctuates whilst idling.
Any help would be much appreciated.

P.S.Replacing engining mounts has helped shaking slightly.
