Throttle Position Sensor Replacement $129.21 - $646.10 Get a Quote

Hi There, The inconsistent throttle response you are describing sounds like you may have a faulty throttle position sensor. The throttle position sensor monitors the throttle position of the throttle plate inside the throttle body in relation to your foot position on the gas pedal. Based upon the inputs from the sensor reading your foot’s position on the pedal, the ECU then makes the direction to supply more or less fuel to the motor. When this sensor is not working properly, this can cause intermittent responses when pressing the gas pedal. I would suggest having a professional from Your Mechanic come to you home to diagnose your vehicle’s running condition.

Rattling sound from front axle.

A rattling sound from under the car could be a loose heat shield. But then again, it could be many other things. I suggest having a certified technician, such as one from YouMechanic, inspect your vehicle firsthand.
