Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Disconnect the negative terminal of the battery to ensure safety during maintenance.
2. Inspect Engine Mounts
  • Use a socket set to remove any components obstructing access to the engine mounts.
  • Visually inspect each engine mount for cracks, separation, or excessive wear.
  • If any mounts are damaged, replace with new components.
3. Address Vacuum Leaks
  • Inspect hoses connected to the intake manifold for cracks or disconnections.
  • Apply a smoke test or use a spray bottle with soapy water around suspected areas to identify leaks.
  • Replace any damaged hoses or gaskets.
4. Replace Spark Plugs and Ignition Coils
  • Remove the ignition coils using a socket set.
  • Take out old spark plugs with a spark plug socket.
  • Install new spark plugs to the manufacturer’s specified torque (usually around 13-15 ft-lbs).
  • Reinstall ignition coils securely.
5. Clean Throttle Body and Idle Air Control Valve
  • Remove the throttle body by disconnecting electrical connectors and removing mounting bolts.
  • Clean the throttle body using throttle body cleaner and a soft cloth.
  • Remove and clean the idle air control valve if accessible or replace it if faulty.
  • Reinstall the throttle body and reconnect all components.
