Q: Inconsistent pedal to actual rpm response, jumpy rpm, no rpm power

asked by on

when i press throttle pedal the actual rpm is mismatched and only last a second before returning to idle position even though my foot remains pressed on the throttle pedal. idle rpm is jumpy and all over the place and now recently brake pedal input to actual braking has diminished considerably, like the vaxlcuum hose isnt connected

Hi There, It sounds like you are describing the symptoms of a failing 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 and inspect your vehicle.
