Q: When accelerating from standing stop engine hesitates

asked by on October 06, 2016

Accelerating when driving on road acts normal only balks from standing stops,

My car has 141000 miles.
My car has an automatic transmission.

I would recommend checking the mass air flow sensor as this is a commonly known part that can cause this kind of loss of power. This regulates the air intake into the fuel injection and ensures a proper air/fuel mixture.

As you may know, when going up hill and altitude changes, so does air density which requires a change in the air/fuel mixture. When this sensor is faulty and this does not happen, you will likely experience this kind of loss in power.

I would recommend having an expert from Your Mechanic come to your home to diagnose your car’s running condition.
