1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during work.
Elevate the vehicle if necessary for access to components.

2. Inspect and Replace Spark Plugs

Remove the engine cover (if applicable).
Disconnect the ignition coils from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect the old plugs for wear and compare with specifications.
Gap the new spark plugs according to manufacturer specifications.
Install new spark plugs and reconnect ignition coils.

3. Clean or Replace Fuel Injectors

Remove the fuel rail from the engine.
Disconnect the fuel lines carefully to avoid spills.
If cleaning, use a fuel injector cleaning kit; if replacing, install new injectors.
Reassemble the fuel rail and reconnect the fuel lines securely.
Turn the ignition to the "ON" position to prime the fuel system and check for leaks.

4. Throttle Position Sensor Testing/Replacement

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector.
Use a multimeter to check the sensor’s resistance and voltage output.
If faulty, remove the old sensor and install a new one, reconnecting the electrical connector.
