95 W124 misfire...I THINK

on a 95 E320 with about 119k the car looses power and I hear very muffled "pops" (not exactly the "I'm-being-shot-at" backfires I would expect) when under sudden acceleration or load as in going up a grade. then suddenly, in what I can only describe as the car "catching up," is there a return to normal power and response times. The car idles super smooth too boot. Any idea on here I should start?

I would start with the three coil connectors. They are notorious for misfires.

Also check to see if you are running copper core OEM non-resistor plugs.

Do a search for Arthur Dalton's posts. He is a treasure trove of information for your car.

When accelerating from stop, you hear and feel that the engine isn't running properly, some backfires etc. but when you are accelerating from stop to kickdown and the car accelerates normally, this indicates a mass air flow problem.
