Intermittent diagnosis 3.8
 

The vehicle in question is a Euro 1982 380SEL with CIS. When first started it runs like new. As it warms up it develops an intermittent skip. There is no pattern to the skip and is completely random. As it reaches normal operating temperature it sometimes feels like it is loading up with fuel. Stomping on the pedal will clear it out momentarily. It has new plugs, cap, rotor, wires. Replaced these as part of normal maintenance. Just turned 150K. Oil pressure runs at 3 Bar drops to 1.5-2 bar at idle. Any thoughts would be appreciated.

Sounds like the mixture needs adjusting or its got a vacuum leak.
