Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working.
Allow the engine to cool down before starting work.

2. Replace Air Filter

Locate the air filter housing.
Open the housing and remove the old air filter.
Install the new air filter, ensuring it fits snugly in place.
Close the housing securely.

3. Inspect and Replace Fuel Filter (if necessary)

Locate the fuel filter along the fuel line.
Depressurize the fuel system by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines using appropriate tools.
Remove and replace the fuel filter, ensuring correct orientation.
Reconnect the fuel lines and reinstall the fuse.

4. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable).
Disconnect the ignition coils from the spark plugs.
Remove old spark plugs using a socket wrench.
Install new spark plugs, torquing to manufacturer specifications (typically around 13-15 ft-lbs).
Reconnect the ignition coils.

5. Test and Replace Throttle Position Sensor (if faulty)

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector.
Remove the sensor by unscrewing it from the throttle body.
Install the new throttle position sensor and reconnect the electrical connector.
