1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.

2. Inspect and Replace Spark Plugs

Remove the engine cover if applicable.
Disconnect the ignition coils and remove them carefully.
Using a spark plug socket, remove the spark plugs.
Inspect for wear; replace plugs if they show signs of damage or excessive wear.
Install new spark plugs with the correct gap (refer to manufacturer specifications).
Reattach the ignition coils and engine cover.

3. Check Engine Mounts

Visually inspect the engine mounts for cracks or separation.
If damaged, support the engine with a jack and remove the bolts securing the mount.
Replace the damaged mount with a new one, ensuring proper alignment.
Torque bolts to specifications as per the service manual.

4. Clean Throttle Body

Disconnect the negative battery terminal.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body.
Reassemble the intake duct and reconnect the battery terminal.

5. Fuel Injector Inspection
