Tools Required: Socket set, jack stands
Raise the front of the vehicle with a jack and securely place jack stands.
Locate the engine mounts and visually inspect for cracks or separation.
If damaged, remove the bolts securing the engine mount to the engine and frame, and replace with new mounts.
Torque bolts to the manufacturer specifications as stated in the service manual.

3. Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench
Remove the ignition coils by unbolting and disconnecting the electrical connectors.
Extract the old spark plugs using a spark plug socket.
Inspect the old plugs and replace with new ones, ensuring they are properly gapped.
Reinstall the ignition coils and reconnect electrical connectors.

4. Clean or Replace Fuel Injectors

Tools Required: Fuel injector cleaner kit or replacement injectors
If cleaning, remove the fuel rail and injectors from the engine.
Use a fuel injector cleaning kit according to the manufacturer's instructions.
If replacing, install new injectors, ensuring O-rings are lubricated and seated properly.
