What prompts you to think it’s the Manifold Absolute Pressure (MAP) sensors fault?
Agree with Pushrod. Also, just to be clear, this vehicle does not have a stand alone "MAP Sensor". It is integrated in another component. Which leads back to wondering what testing has been performed, what trouble codes are present.
