Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety during the process.

2. Inspect and Replace Air Filter

Locate the air filter housing (usually near the engine).
Remove the housing cover using a socket set.
Take out the old air filter and inspect for dirt and damage.
Install a new air filter that meets OEM specifications.
Reassemble the housing cover and reconnect the battery.

3. Clean or Replace Mass Airflow Sensor

Locate the MAF sensor in the intake duct.
Disconnect the electrical connector and remove the sensor using a screwdriver.
Clean the sensor with MAF cleaner or replace it if necessary.
Reinstall the sensor and reconnect the electrical connector.

4. Inspect Fuel Injectors

Locate the fuel injectors on the fuel rail.
Check for any signs of fuel leaks or blockages.
Use a fuel injector cleaner if they are clogged, or replace them if damaged.

5. Test Fuel Pressure

Attach a fuel pressure gauge to the fuel rail’s test port.
Turn the ignition key to the "ON" position without starting the engine to check the pressure reading.
Compare the reading with specifications in the service manual; replace the fuel pump if pressure is low.
