Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, inspection mirror, vacuum gauge.
  • Ensure the vehicle is parked on a level surface and the engine is cooled down.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Replace Engine Mounts
  1. Locate Engine Mounts: Identify the engine mounts connected to the engine and chassis.
  2. Check Condition: Use an inspection mirror to check for cracks or separation in the rubber of the mounts.
  3. Remove Old Mounts:
    • Use a socket set to remove the bolts securing the engine mounts to the engine and chassis.
    • Carefully lift the engine slightly with a jack to relieve pressure on the mounts.
  4. Install New Mounts:
    • Position the new mounts in place and hand-tighten the bolts.
    • Torque the bolts to manufacturer specifications (check service manual for torque values).
  5. Reconnect Battery: Reconnect the negative battery terminal.
3. Clean or Replace Idle Air Control Valve
  1. Locate the IAC Valve: Find the IAC valve on the throttle body.
  2. Remove the Valve: Disconnect the electrical connector and unscrew the mounting bolts using a socket set.
  3. Clean or Replace:
    • If cleaning, use throttle body cleaner to remove carbon deposits.
    • If replacing, install the new IAC valve, ensuring a proper seal.
  4. Reconnect Everything: Reattach the connector and secure the valve with bolts.
4. Inspect and Replace Spark Plugs
  1. Remove Ignition Coils: Use a socket set to remove the bolts securing the ignition coils, then carefully pull them out.
  2. Check Spark Plugs: Inspect the spark plugs for wear or carbon buildup; replace if necessary.
  3. Install New Spark Plugs: Using a torque wrench, install new spark plugs to the manufacturer’s torque specifications.
  4. Reinstall Ignition Coils: Secure the coils back in place and reconnect the electrical connectors.
