1985 Mercedes Benz 380SL Base 8 Cyl 3.80L

Engine

Engine cuts out/comes back to life

This is happening over 50mph, the tach drops or swings, and the engine looses some power---not all. It seems like some of the cylinders are not firing, then it comes back. Is this ignition coil, or ignition amplifier?

Check the following possibilities; loose / corroded battery negative cable connection - at the battery or at the chassis connection point, plugged / faulty fuel filter.

How many miles on the fuel filter or since the last filter change? Check the various on-line sources; for the replacement parts; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. They list the fuel filter from around $9.80 for your vehicle.
