Solution

1. Preparation

Gather tools and parts.
Disconnect the negative terminal of the battery to avoid electrical shorts.
Allow the engine to cool if it has been running.

2. Replace Air Filter

Locate the air filter housing.
Remove the clips or screws securing the housing cover.
Take out the old air filter and insert the new one, ensuring a snug fit.
Reattach the housing cover and secure it.

3. Check and Replace Fuel Filter

Identify the fuel filter location (consult the service manual if necessary).
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the fuel filter using appropriate line wrenches.
Remove the old fuel filter and install the new one, ensuring correct orientation.
Reconnect the fuel lines and replace the fuel pump relay.

4. Inspect and Replace Spark Plugs

Remove the engine cover if applicable.
Use a socket and ratchet to remove the spark plug wire.
Unscrew the old spark plug with a spark plug socket.
Check the gap on the new spark plug and adjust as necessary.
Install the new spark plug and reconnect the wire.
Repeat for all spark plugs.

5. Clean Throttle Body

Remove the intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and the inside of the throttle body.
Reassemble the intake duct and ensure all connections are secure.

6. Test Drive

Reconnect the battery terminal.
Start the engine and allow it to idle for a few minutes.
Test drive the vehicle to ensure improved acceleration and responsiveness.
