Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Clean Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body while manually opening the throttle plate.
Wipe away carbon deposits with a clean cloth.
Reattach the intake duct securely, ensuring all clamps are tightened.

3. Replace Air Filter

Locate the air filter housing, usually accessible with a few clips or screws.
Remove the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it is seated properly in the housing.
Secure the housing back in place.

4. Test and Clean MAF Sensor

Locate the MAF sensor, typically found near the air intake.
Disconnect the electrical connector and carefully remove the MAF sensor.
Using MAF cleaner, spray the sensor elements and allow it to dry completely before reinstalling.
Reconnect the sensor and ensure all connections are secure.

5. Fuel Pressure Test

Connect a fuel pressure gauge to the fuel rail service port.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading against the manufacturer specifications.
If the pressure is low, inspect the fuel pump and replace if necessary.
