Hi there. This is an indication of a faulty throttle position sensor. This is a sensor that monitors the position of your foot on the gas pedal relative to the throttle plate inside the throttle body.

As you move your foot up and down on the pedal, this sensor relays this information to the car’s computer which then controls the amount of fuel it provides to the fuel injection system. When this is not working properly, you may experience the symptoms you have described. If you would like to move forward with a throttle position sensor replacement, or have a professional diagnose the loss of power problem, then a certified technician from YourMechanic can visit your car’s location to perform services.
