Q: Reduced speed and hesitation

asked by on

while driving speed reduces to 30 miles
My car has an automatic transmission.

Hello, There are a number of things that may cause the car to hesitate when accelerating such as low fuel pressure, a dirty or faulty mass air flow sensor, clogged or dirty fuel injectors, a faulty throttle position sensor or potentially a bad fuel pump. Additionally, this may be caused by an internal fault detected in the transmission causing the computer to put the car into a "safe mode" or limp mode to prevent further damage. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
