Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a screwdriver.
Take out the air filter and inspect it for dirt; replace if necessary.
Reinstall the air filter and secure the housing cover.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Open the throttle plate manually to clean the edges.
Reattach the intake duct securely.

4. Check and Replace Spark Plugs

Remove the ignition coils by unbolting them and disconnecting the electrical connectors.
Unscrew the spark plugs using a socket wrench and inspect them for wear or carbon deposits.
Replace worn spark plugs with new ones, ensuring the correct gap (typically 0.044 in / 1.1 mm).
Reinstall the ignition coils, tightening to the manufacturer’s torque specification.

5. Inspect and Clean MAF Sensor

Disconnect the MAF sensor electrical connector.
Remove the MAF sensor from the intake.
Spray MAF sensor cleaner on the sensor element; do not touch it with your fingers.
Reinstall the MAF sensor and reconnect the electrical connector.

6. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading.
If the pressure is below specifications, inspect the fuel pump and fuel filter for issues.
