Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety before working on electrical components.

2. Check and Replace Fuel Filter

Locate the fuel filter (usually found along the fuel line).
Use a socket set to remove the mounting bolts and disconnect fuel lines (use caution as fuel may spill).
Install the new fuel filter, ensuring all connections are secure and properly aligned.
Reconnect the battery and prime the fuel system by turning the ignition on without starting the engine.

3. Inspect and Replace Spark Plugs

Remove the engine cover, if applicable, using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove old spark plugs.
Inspect new spark plugs for correct gap and thread type, then install them.
Reinstall the ignition coils and cover.

4. Test and Replace Throttle Position Sensor (if necessary)

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the sensor.
Use a multimeter to test the sensor output according to manufacturer specifications.
If the sensor is faulty, unbolt it from the throttle body and replace it with a new one.
Reconnect the electrical connector and ensure all connections are secure.
