Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery for safety before starting any repairs.

2. Replace Engine Mounts (if necessary)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts; they are usually positioned on either side of the engine.
3. Remove the bolts securing the engine mounts using a socket set.
4. Carefully lift the engine slightly using a hoist or jack to relieve pressure on the mounts.
5. Remove the old engine mounts and install new mounts, ensuring they are properly aligned.
6. Torque the mounting bolts to the manufacturer's specified torque values.

3. Replace Spark Plugs and Ignition Coils (if necessary)

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the electrical connectors from the ignition coils.
3. Unscrew the ignition coils and remove them from the spark plugs.
4. Use a spark plug socket to remove the old spark plugs.
5. Install new spark plugs, ensuring the gap is set to the manufacturer’s specifications.
6. Reinstall the ignition coils and reconnect the electrical connectors.

4. Clean or Replace Fuel Injectors (if necessary)

Sub-steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
2. Disconnect the fuel lines from the injectors, being cautious of fuel spillage.
3. Remove the fuel injectors from the fuel rail.
4. Clean the injectors using a fuel injector cleaning kit or replace them if they're faulty.
5. Reinstall the clean or new injectors and reconnect the fuel lines.
