Solution

1. Preparation

Gather tools and parts required for repair.
Disconnect the battery to prevent any electrical shorts during the repair.
Ensure the vehicle is on a level surface and secure it with jack stands if necessary.

2. Inspect and Replace Fuel Filter

Locate the fuel filter based on the vehicle's service manual.
Use a wrench to disconnect the fuel lines from the filter (ensure to have a rag ready to catch any spilled fuel).
Remove the old fuel filter and replace it with a new one, ensuring the flow direction matches the vehicle specifications.
Reconnect the fuel lines securely and check for leaks.

3. Clean or Replace Air Filter

Open the air intake housing and remove the old air filter.
Inspect the filter; if dirty, clean it or replace it with a new one.
Reassemble the air intake housing, ensuring all clamps are tightened.

4. Replace Spark Plugs

Remove the ignition coils or spark plug wires to access the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Check the gap on the new spark plugs according to manufacturer specifications and install them.
Reinstall the ignition coils or plug wires.

5. Clean MAF Sensor

Locate the MAF sensor in the air intake duct.
Disconnect the electrical connector and remove the sensor from the duct.
Spray MAF sensor cleaner on the sensor element and let it dry completely before reinstalling.
