Why does my car lose power when I press the accelerator?
When you press the accelerator, it sends more fuel through the filter and not as much can get through. Also, a dirty fuel filter is a common reason why your car is blowing white smoke and losing power. The dirt in the cylinders is burned along with the fuel and this causes smoke to come out of the exhaust.
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.
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 to do if your car loses power?
Visit a mechanic if this is the case or clean the catalytic converter by yourself at home. The catalytic converter filters the exhaust system once the fuel has gone through the engine. However, there are various filters in an internal combustion engine. One of the other most important ones is the fuel filter.
