I've notice lately that, when cold, the E420 just doesn't want to go - I feel safer stomping on the accel pedal on the 300D when it is cold, than with the 420....at least I know the 300D won't stall.

OK....When cold, I step on the "gas" to get into traffic, and not much happens....either it brumbles* and then finally catches itself, or it nearly stalls (I had it stall once) and I let of the gas quickly, so it won't stall - then try it again.
If this thing had a carb, I'd say the accelerator pump is shot.

O2 sensor?

Thank you for your thoughts!

*"brumble": a low rumble ...the kind you hear when a motor is bogging - Secondaries are open, but it just kinda goes baaaaaaaah.
