Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shock.
• Gather necessary tools and parts.

2. Inspect and Replace Spark Plugs

1. Remove the engine cover (if applicable) using a socket set.
2. Disconnect the ignition coils from the spark plugs.
3. Use a spark plug socket and ratchet to remove the old spark plugs.
4. Inspect the spark plugs for wear; replace with new spark plugs as needed (refer to owner’s manual for specifications).
5. Reinstall the ignition coils and engine cover.

3. Check and Replace Ignition Coils (if necessary)

1. If the OBD-II scanner indicates faulty ignition coils, remove the ignition coil connectors.
2. Unbolt the ignition coils and carefully pull them out of the engine.
3. Install new ignition coils by reversing the removal process, ensuring proper seating and connection.

4. Inspect and Clean Fuel Injectors

1. If fuel injectors are suspected to be clogged, remove them according to the service manual.
2. Use a fuel injector cleaning kit to clean the injectors.
3. Reinstall the cleaned or new fuel injectors, ensuring proper sealing.

5. Check Engine Mounts

1. Visually inspect the engine mounts for any cracks or signs of wear.
2. If damaged, remove the bolts securing the engine mount to the frame and engine.
3. Install new engine mounts as per specifications, tightening bolts to the manufacturer’s torque values.
