Mercedes-Benz Viano can't accelerate.

What the subject wants to ask is "What is the reason why Mercedes-Benz Viano can't accelerate?" The engine is low in fuel and the fuel filter screen is blocked.

1. When the engine is running, there is not enough fuel or air, so the pipelines and parts of the fuel system and many parts of the air intake system are blocked, such as oil pipes, air filters, throttle valves and other parts, which will lead to the abnormal situation that the car cannot accelerate.

2. The fuel filter screen is blocked: after the throttle is increased, the fuel supply is insufficient, resulting in flameout.
