Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket.
Remove the ignition coil cover if applicable.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils using a socket wrench.
Remove old spark plugs using a spark plug socket and ratchet.
Inspect new spark plugs for correct gap and install them to torque specifications (typically 13-15 ft-lbs).
Reinstall ignition coils and reconnect electrical connectors.

3. Clean or Replace Air Filter

Tools Required: Screwdriver (if air filter housing is bolted).
Open the air filter housing by removing screws or clips.
Remove the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it is seated correctly.

4. Inspect and Replace Fuel Injectors (if necessary)

Tools Required: Fuel injector removal tool, socket set.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines and electrical connectors from the injectors.
Remove the old fuel injectors.
Install new fuel injectors and reconnect fuel lines and electrical connectors.
