... now appears to be the accelerator. Periodically, when I step down the vehicle does little, unless I push it almost all the way to the floor.
Is this car "DBW"/electronic accelerator? What should be tested/checked?

What car???????
sorry
'97 E320
If it was an older transmission with kickdown cable, I would say the cable needs to be replaced/tightened. In a tranny that uses vacuum kickdown, I would guess clogged lines or bad switch. In your car, well, someone is telling it to shift wrong. If it has a computer, it could either be the computer or the sensors it needs to know what is going on.
Where should I begin looking?

Does the car exhibit any other unusual symptoms such as sporadic rough idle or pinging? Also, what happens if you manually donwshift the tranny?
Nothing per the first question. I'll check the 2nd issues a little later. Thanks,
Collin
No problems related to the first question. I'll check against the 2nd question a little later & report back. Thanks,

It behaves the same in all gears whe the condition occurs.

Does it stumble? Or just not react? The reason I ask is that if it stumbles I wonder if this could be some type of EGR issue, but I would have expected at least a periodic rough idle if that was the case.
It doesn't react until the pedal is most of the way down. It does make me think of a vacuum leak. But I know nothing about this 'mission design.

Suggest you think about the air mass sensor.
Tell me more.
