Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
Ensure the vehicle is parked on a flat surface and the engine is cool before beginning repairs.

2. Address Engine Mounts

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Remove any components obstructing access to engine mounts (e.g., air intake assembly).
3. Inspect the engine mounts for cracks or signs of fluid leaks.
4. If damaged, remove the old mounts by unbolting them from the engine and chassis.
5. Install new engine mounts and torque them to manufacturer specifications (typically found in the service manual).

3. Check and Replace Spark Plugs (if necessary)

Sub-steps:
1. Remove the ignition coil connectors and unscrew the coils.
2. Extract the spark plugs using a spark plug socket.
3. Inspect the spark plugs for fouling or wear; replace if necessary.
4. Gap new spark plugs to manufacturer's specifications before installation.
5. Reinstall the spark plugs and ignition coils, ensuring they are securely fastened.

4. Inspect Fuel Injectors

Sub-steps:
1. Disconnect the fuel lines and electrical connectors from the fuel injectors.
2. Remove the fuel rail to access the injectors.
3. Inspect each injector for clogs or damage; clean or replace as needed.
4. Reassemble the fuel rail and reconnect all lines and connectors securely.
