Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to avoid any electrical issues while working.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt and blockages.
Install a new air filter (ensure it matches OEM specifications).

3. Clean Throttle Body

Remove the throttle body assembly by disconnecting the throttle position sensor and any intake hoses.
Use throttle body cleaner and a soft cloth to clean the interior surfaces.
Reinstall the throttle body, ensuring all connections are secure.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers and coils using a socket set.
Remove the spark plugs using a spark plug socket, inspecting them for wear or carbon buildup.
Install new spark plugs, ensuring they are gapped to manufacturer specifications.

5. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter (check service manual for location).
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines and replace the filter with a new one, ensuring proper orientation.
