Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Allow the engine to cool before proceeding.
2. Inspect Engine Mounts
  • Tools Required: Jack and jack stands, socket set
  • Raise the front of the vehicle using a jack and secure it on jack stands.
  • Visually inspect each engine mount for cracks, tears, or displacement.
  • If a mount is damaged, proceed to the next step.
3. Replace Damaged Engine Mounts
  • Tools Required: Socket set, torque wrench
  • Remove the bolts securing the damaged engine mount to the engine and chassis.
  • Position the new engine mount and secure it with bolts, ensuring they are tightened to the manufacturer's specified torque value.
  • Repeat for any additional damaged mounts.
4. Check and Replace Spark Plugs/Ignition Coils
  • Tools Required: Socket set, torque wrench, spark plug gap tool
  • Remove the ignition coils by disconnecting the electrical connectors and removing the mounting bolts.
  • Extract the spark plugs using a spark plug socket.
  • Inspect and replace worn spark plugs; ensure the gap is set to the manufacturer specifications.
  • Reinstall ignition coils, securing them with bolts and reconnecting the connectors.
5. Clean the Idle Air Control Valve
  • Tools Required: Cleaning solvent, soft brush
  • Locate the IACV, disconnect the electrical connector and carefully remove it from the intake.
  • Clean the valve and its passages thoroughly with cleaning solvent and a soft brush.
  • Reinstall the IACV and reconnect the electrical connector.
6. Test for Vacuum Leaks
  • Tools Required: Smoke machine (if available) or a can of carburetor cleaner
  • If using a smoke machine, connect it to the intake and look for smoke escaping from any cracks or loose connections.
  • Alternatively, spray carburetor cleaner around the intake manifold and vacuum lines; an increase in engine RPM indicates a leak.
  • Repair or replace any damaged hoses or gaskets found during this inspection.
