Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, multimeter, socket set, torque wrench, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt and blockages.
Replace with a new air filter if dirty, ensuring proper seating in the housing.
Reassemble the air filter housing cover and tighten to manufacturer specifications.

3. Test and Replace Fuel Pump (if necessary)

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition to the 'ON' position (do not start the engine) and check the pressure reading.
If pressure is below specifications (refer to service manual for values), replace the fuel pump:
- Disconnect the negative battery terminal.
- Relieve fuel system pressure by removing the fuel pump relay or fuse and cranking the engine.
- Remove the fuel tank (refer to service manual for steps) and replace the fuel pump with a new unit.
- Reassemble the fuel tank, reconnect the battery, and test the system.

4. Replace Spark Plugs and Ignition Coils (if faulty)

Remove the ignition coil cover, if applicable.
Disconnect the electrical connectors from the ignition coils.
Remove the bolts holding the coils in place and take them out.
Check spark plugs for wear; replace if necessary.
Install new spark plugs and ignition coils, tightening to recommended torque specs.

5. Clean or Replace MAF Sensor

Locate the MAF sensor in the air intake duct.
Disconnect the electrical connector and remove the sensor.
Clean the MAF sensor using MAF cleaner spray.
If damaged, replace it with a new MAF sensor.
Reinstall the sensor and reconnect the electrical connector.
