Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts.

2. Replace Fuel Filter (if clogged)

Locate the fuel filter in the fuel line.
Use a wrench to disconnect the fuel lines from the filter (caution: fuel may spill).
Remove the old fuel filter and install the new one, ensuring proper orientation.
Reconnect the fuel lines and check for leaks.

3. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable) and disconnect the ignition coils.
Use a spark plug socket to remove the old spark plugs.
Inspect the spark plugs for wear; replace with OEM or equivalent plugs.
Reinstall the ignition coils and cover.

4. Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reinstall the air intake duct securely.

5. Test and Replace the MAF Sensor (if faulty)

Disconnect the MAF sensor electrical connector.
Remove the sensor from the air intake duct.
Install a new MAF sensor if testing reveals incorrect readings.
Reconnect the electrical connector and ensure it is secure.
