Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Components

a. Fuel Filter

Locate the fuel filter along the fuel line.
Use a wrench to disconnect the fuel lines (wear safety goggles).
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and check for leaks.

b. Check and Replace Spark Plugs

Remove the ignition coil cover using a socket set.
Disconnect the ignition coils and remove them.
Unscrew the spark plugs using a spark plug socket.
Inspect the old spark plugs for wear and replace them if necessary (use recommended gap).
Reinstall the spark plugs and ignition coils, securing them to factory torque specifications.

3. Clean the Throttle Body

Remove the throttle body from the intake manifold (if applicable).
Use throttle body cleaner and a soft brush to clean the inside.
Reinstall the throttle body, ensuring gaskets are in place.

4. Test and Replace the Fuel Pump (if necessary)

Locate the fuel pump in the fuel tank.
Disconnect the fuel lines and electrical connectors.
Remove the pump assembly and replace it with a new one.
Reassemble and reconnect all components, ensuring no leaks.
