Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.
Gather necessary tools and parts for the repair process.

2. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a clean cloth to remove carbon buildup from the throttle plate and bore.
Reattach the air intake duct securely.

3. Check and Replace Spark Plugs

Remove the ignition coil(s) for access to the spark plugs using a socket set.
Inspect the spark plugs for wear; replace if necessary (use OEM specifications for gap).
Reinstall ignition coils and ensure they are seated properly.

4. Replace the Fuel Filter

Locate the fuel filter and relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter (be cautious of residual fuel).
Install the new fuel filter, ensuring that the flow direction is correct.
Reconnect the fuel lines securely.

5. Verify Fuel Pressure

Reconnect the fuel pump fuse and turn the ignition on (do not start) to build pressure.
Use a fuel pressure gauge to check if the pressure meets manufacturer specifications.
If pressure is low, investigate further into the fuel pump or fuel lines.
