Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to avoid electrical shorts.
2. Replace Spark Plugs
  • Remove the engine cover if applicable.
  • Use a socket set to carefully remove the spark plugs.
  • Inspect old spark plugs for wear; replace with new ones if necessary.
  • Torque the new spark plugs to the manufacturer's specified value (usually around 13-16 lb-ft).
3. Clean or Replace Idle Air Control Valve (IAC)
  • Locate the IAC valve; it is typically mounted on or near the throttle body.
  • Remove the electrical connector from the IAC.
  • Unscrew and remove the IAC from its mounting.
  • If cleaning, use a throttle body cleaner to remove carbon deposits; otherwise, replace it with a new unit.
  • Reinstall the IAC and reconnect the electrical harness.
4. Inspect and Replace Air Filter
  • Open the air filter housing; remove the old air filter.
  • Inspect the housing for dirt or debris.
  • Install a new air filter, ensuring it fits snugly in place.
5. Check for Vacuum Leaks
  • Inspect all vacuum hoses connected to the intake manifold for cracks.
  • Replace any damaged vacuum hoses as necessary.
  • Use a smoke machine or carburetor cleaner to check for leaks while the engine is running.
