Hi, this is a common symptom of a clogged fuel filter that is straining the fuel pump itself.

When you accelerate, this initiates a rapid fuel flow through the lines. if the filter cant pass the proper amount, its will stall or hesitate the engine and cause sputtering or loss of power. due to this clogged filter, the pump cant keep up with your acceleration demands at this time. the reason for the power pick up upon De acceleration, is because the lower amount of fuel is able to pass through quite easily but, as soon as you demand more power, the clog will obstruct the more intense flow of fuel to the injectors.

Simply replacing the fuel filter and pump will fix this issue.

Please rate and god bless:)

Try changing the fuel filter. If it clogs up the engine won't get the fuel it needs to run at wide throttle openings, the engine will ****** the timing, and you'll lose power. With less throttle the filter can flow well enough for the engine to run properly.

2001 E220 CDI exhaust tail pipe black smoke on acceleration


Black smoke is almost always an indication that the air/ fuel mix (ratio), is too rich. I would try to find out if the just cleaned the injectors or were they replaced. Cleaning injectors and sometimes leave irregularly shaped orifices. Besure the air filter is clean. This can effect mix also.
Good Luck and hope this helps.
