why does my Genesis G70 engine shake when I accelerate

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the battery to ensure safety during repairs.
• Allow the engine to cool down if it has been running.

2. Inspect and Replace Engine Mounts (if damaged)

• Sub-steps:
  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Locate the engine mounts (typically found on either side of the engine).
  3. Visually inspect the mounts for cracks, tears, or separation.
  4. If damaged, remove the bolts securing the mounts using a socket set.
  5. Replace with new engine mounts, ensuring they are oriented correctly.
  6. Torque bolts to manufacturer specifications (typically around 45-60 ft-lbs, check service manual for specifics).

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

• Sub-steps:
  1. Remove the engine cover (if applicable) to access the ignition components.
  2. Disconnect the electrical connectors from the ignition coils.
  3. Remove the ignition coils by unscrewing them from the cylinder head.
  4. Extract the old spark plugs using a spark plug socket.
  5. Install new spark plugs, torquing them to the manufacturer’s specification (usually around 13-16 ft-lbs).
  6. Reinstall and secure the ignition coils, reconnecting the electrical connectors.

4. Inspect and Clean Fuel Injectors (if necessary)

• Sub-steps:
  1. Disconnect the fuel pump relay to relieve fuel pressure.
  2. Remove the intake manifold (if required) to access the fuel rail and injectors.
  3. Disconnect the fuel lines and electrical connectors from the fuel injectors.
  4. Remove the fuel injectors from the fuel rail.
  5. Clean the injectors using a professional injector cleaner or replace them if they are faulty.
  6. Reinstall the injectors, ensuring proper seating and securing all connections.
