Ever wondered how a fuel injection engine works - what do all those sensors do? -Mass airflow sensor -Oxygen sensor -Throttle position sensor -Coolant temperature sensor -Voltage sensor -Manifold absolute pressure sensor -Engine speed sensor Did you know the gas pedal should be called the air pedal? I found an excellent article HERE. In-fact I just cleaned my 'throttle body' and tick-over is a lot smoother now! Rex.
