Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool down before proceeding.

2. Inspect and Clean the Air Intake System

Remove the air intake duct.
Inspect the air filter; replace if clogged.
Clean the MAF sensor using MAF cleaner spray.
Reassemble the air intake components ensuring all connections are secure.

3. Check and Replace Spark Plugs

Remove the ignition coil covers.
Disconnect the ignition coils and remove them.
Unscrew the old spark plugs using a spark plug socket.
Check the gap on new spark plugs and install them with a torque value of 13 lb-ft.
Reinstall the ignition coils and covers.

4. Test and Replace the Fuel Filter (if applicable)

Locate the fuel filter; refer to the service manual for the exact position.
Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter and replace it with a new filter.
Reconnect the fuel lines and restore fuel pressure by reinserting the fuse.

5. Inspect Throttle Body

Remove the throttle body from the intake manifold.
Clean the throttle plate and bore with throttle body cleaner.
Reinstall the throttle body and ensure all electrical connections are secure.
