What causes no power when accelerating loss of power?
A faulty throttle position sensor can most certainly duplicate all of the symptoms that your Mercedes is experiencing, however a faulty fuel pump or even a defective mass airflow sensor can be the cause to these issues too.
What causes a car to lose power after 70K miles?
The MAF (Mass Air Flow) Sensor. A bad or going-bad MAF can cause the loss of power. These are usually good to 70K miles. A bad MAF sensor might produce a sudden reduction in car power, but the normal failure mode is a gradual loss of power over weeks.
Can a bad MAF cause loss of power?
A bad or going-bad MAF can cause the loss of power. These are usually good to 70K miles. A bad MAF sensor might produce a sudden reduction in car power, but the normal failure mode is a gradual loss of power over weeks. Your engine light may come on if the sensor only has intermittent failure.
Why is my car losing power at low speeds?
If the pressure is low the fuel injectors will not be able to spray the correct amount of fuel into the combustion chamber and that will result in a loss of power. A faulty fuel pump will not pose problems at low speeds but when you are looking for quick acceleration you might be left wanting.

Why does my Corrolla lose power during acceleration?
Immediately the check engine light came on. That is when the O2 sensor had to be replaced (by another mechanic). After that is when the problem with loss of power started. The fuel filter I’m told is designed to not need regular replacement. It is part of the the fuel pump inside the tank. The air filter is fine. The check engine light is not on.
What do you need to know about slow acceleration?
Since the initial problem of slow acceleration did not produce a check engine light I was reluctant to mess with any of the other sensors. What you need for proper engine operation is a) air, b) fuel & c) ignition.
