Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Air Filter

Remove the air filter housing cover (tools: socket set).
Take out the old air filter and inspect for dirt or damage.
Install a new air filter, ensuring it is seated properly.
Reassemble the air filter housing cover.

3. Fuel Filter Inspection and Replacement

Locate the fuel filter (refer to the vehicle's service manual for location).
Depressurize the fuel system by removing the fuel pump relay and starting the engine until it stalls.
Disconnect fuel lines and remove the old filter (tools: wrench set).
Install the new fuel filter, ensuring correct orientation and secure connections.

4. Test Fuel Pump Pressure

Connect a fuel pressure gauge to the fuel rail (tools: fuel pressure gauge).
Turn the ignition key to the "ON" position without starting the engine and check the pressure reading.
Compare the reading to manufacturer specifications; replace the fuel pump if pressure is low.

5. Throttle Body Cleaning

Remove the throttle body from the intake manifold (tools: socket set).
Clean the throttle body with a throttle body cleaner and a soft brush.
Reinstall the throttle body, ensuring proper gasket alignment and tightening to manufacturer torque specifications.

6. Spark Plug Inspection and Replacement

Remove the ignition coils (if applicable) to access the spark plugs (tools: socket set).
Inspect the spark plugs for wear and carbon buildup.
Replace with new spark plugs (ensure correct gap as per specifications).
Reinstall ignition coils and reconnect all electrical connectors.
