Ensure the vehicle is parked on a level surface with the engine off and cool.

2. Replace Spark Plugs

Remove the engine cover if applicable.
Disconnect the ignition coils from the spark plugs.
Use a socket wrench to remove the old spark plugs.
Inspect the spark plug holes for debris and use compressed air if necessary.
Install new spark plugs, ensuring they are properly gapped according to manufacturer specifications.
Reattach the ignition coils and engine cover.

3. Inspect and Replace Engine Mounts

Lift the vehicle using a jack and secure with jack stands.
Visually inspect the engine mounts for cracks or signs of wear.
Use a socket set to remove the bolts securing the damaged engine mount.
Replace with new engine mounts, ensuring they are torqued to manufacturer specifications.
Lower the vehicle and start the engine, checking for vibrations.

4. Clean Fuel Injectors

Disconnect the fuel line and relieve fuel pressure according to the vehicle’s service manual.
Remove the fuel injectors from the intake manifold.
Use a fuel injector cleaning kit to clean the injectors, following the kit instructions.
Reinstall the cleaned injectors, ensuring proper alignment and sealing.
Reconnect the fuel line.
