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

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove any components obstructing access to the engine mounts.
Use a pry bar to gently lift the engine and relieve pressure on the mounts.
Remove the bolts securing the engine mounts to the engine and frame.
Replace with new engine mounts, ensuring proper alignment.
Torque the mount bolts to manufacturer specifications (typically around 40-50 ft-lbs).

3. Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench, dielectric grease
Disconnect the ignition coils and remove them to access the spark plugs.
Remove the old spark plugs using a spark plug socket.
Inspect and clean the spark plug wells for debris.
Install new spark plugs, applying dielectric grease to the threads.
Torque to manufacturer specifications (usually 13-15 ft-lbs).

4. Clean or Replace Fuel Injectors

Tools Required: Fuel injector cleaning kit or replacement injectors, safety goggles
Follow safety procedures to relieve fuel pressure before removal.
Disconnect fuel lines from the injectors and remove the injectors from the rail.
Clean injectors using a cleaning kit or replace them if necessary.
Reinstall injectors, ensuring O-rings are lubricated and seated correctly.
