Car: 2001 W210 E55 with stock unmodified v8, 101k miles

So far: Replaced plugs, wires, O2 sensors, engine mounts, throttle actuator, and MAF. All other services performed according to schedule since new.

Symptoms: Intermittent engine stumble or miss immediately after coming to a complete stop. Usually this occurs after the first full complete stop after being started (i.e., not after pulling out of a parking spot, but after reaching 40mph or so and having to fully stop for a red light). Engine will not stumble or miss in neutral or park if left alone to idle. Only occurs when coming to a stop and vehicle begins lurching/shaking/surging as if not running on all cylinders. The troubling part is that NO CODES are being thrown during or after these episodes!

Engine power in all RPMs very good otherwise and good throttle response overall.

Any ideas?? thanks!
