Solution

1. Preparation

Gather tools required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, cleaning supplies.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Remove the air intake assembly.
Take out the air filter and inspect for dirt or damage.
Replace with a new air filter if necessary.
Reassemble the air intake assembly.

3. Check and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Use appropriate tools to disconnect the fuel lines (ensure fuel system is depressurized).
Replace the old fuel filter with a new one.
Reconnect the fuel lines securely.

4. Clean Throttle Body

Remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft cloth to clean the interior surfaces.
Reinstall the throttle body and ensure it is securely fastened.

5. Inspect and Replace Spark Plugs

Remove the ignition coils from the spark plug locations.
Use a spark plug socket to remove the spark plugs.
Inspect the spark plugs for wear; replace them if they are worn or fouled.
Reinstall new spark plugs and reattach ignition coils.

6. Clean or Replace MAF Sensor

Disconnect the MAF sensor connector and remove it from the air intake.
Use MAF sensor cleaner to clean the sensor element carefully.
Reinstall the MAF sensor and reconnect the wiring harness.
