3. Clean the sensor with MAF sensor cleaner to remove any dirt or debris.
4. Allow it to dry completely before reinstalling.
Tools Required: MAF sensor cleaner, screwdriver set.

3. Check and Replace Fuel Injectors (if necessary)

Sub-steps:
1. Remove the engine cover (if applicable) to access fuel injectors.
2. Disconnect the electrical connectors from the injectors.
3. Remove the fuel rail bolts and gently pull the rail away with the injectors attached.
4. Inspect injectors for clogs; replace if necessary.
5. Reassemble fuel rail and reconnect electrical connectors.
Tools Required: Socket set, torque wrench.

4. Replace Air Filter

Sub-steps:
1. Open the air intake housing.
2. Remove the old air filter and inspect for any damage.
3. Install a new, clean air filter that meets OEM specifications.
4. Close the air intake housing securely.
Parts Required: New air filter.

5. Verify Fuel Pressure

Sub-steps:
1. Attach a fuel pressure gauge to the fuel rail test port.
2. Turn the ignition to the ON position (do not start) to check the pressure.
3. Ensure the pressure matches specifications; replace the fuel pump if low.
Tools Required: Fuel pressure gauge.
