Solution
1. Preparation
  • Gather necessary tools and replacement parts.
  • Disconnect the battery to ensure safety while working on the vehicle.
2. Inspect and Replace Engine Mounts
  1. Lift the Vehicle: Use a jack to lift the front of the vehicle and secure it with jack stands.
  2. Remove the Engine Mounts:
    • Locate the engine mounts and remove the bolts securing them to the engine and chassis using a socket set.
    • Carefully support the engine with a jack if necessary.
  3. Install New Mounts:
    • Position new engine mounts in place and hand-tighten the bolts.
    • Torque the bolts to the manufacturer's specifications (typically 40-50 ft-lbs).
3. Replace Spark Plugs
  1. Remove Ignition Coils: If applicable, disconnect the electrical connectors and remove the ignition coils.
  2. Extract Old Spark Plugs: Use a spark plug socket to unscrew the old spark plugs from the engine.
  3. Install New Spark Plugs:
    • Apply anti-seize compound to the threads of the new spark plugs.
    • Screw in the new plugs by hand, then torque them to the manufacturer's specification (usually around 15-20 ft-lbs).
4. Check and Adjust Idle Speed
  1. Reconnect Battery: Ensure the battery is reconnected after all previous work.
  2. Start Engine: Allow the engine to warm up to operating temperature.
  3. Adjust Idle Speed: If necessary, adjust the idle speed via the throttle body adjustment screw, ensuring it is within OEM specifications.
