Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to avoid any electrical shorts during repairs.

2. Inspect and Replace Engine Mounts

• Tools Required: Socket set, torque wrench, pry bar
• Sub-steps:
  1. Locate the engine mounts (typically at the front and rear of the engine).
  2. Use the socket set to remove the bolts securing the engine mounts to the engine and chassis.
  3. Carefully lift the engine slightly using a jack and a wooden block to avoid damage.
  4. Remove the old engine mounts and replace them with new ones.
  5. Torque the bolts to the manufacturer's specifications (consult repair manual for exact torque values).

  4. Replace any damaged hoses and ensure all connections are secure.

4. Clean Fuel Injectors

• Tools Required: Fuel injector cleaning kit, safety goggles
• Sub-steps:
  1. Remove the fuel injectors from the engine (consult repair manual for specific procedures).
  2. Use the fuel injector cleaning kit to clean the injectors according to the manufacturer's instructions.
  3. Reinstall the cleaned injectors ensuring proper sealing.

5. Inspect and Replace Ignition Components

• Tools Required: Spark plug socket, torque wrench, multimeter
• Sub-steps:
  1. Remove the spark plugs and inspect them for wear or fouling.
  2. Replace spark plugs if necessary, ensuring they are gapped correctly.
  3. Test ignition coils using a multimeter for proper resistance.
  4. Replace any faulty coils.
