Solution
1. Preparation
  • Gather tools and parts needed for repairs.
  • Disconnect the negative battery terminal to ensure safety during repairs.
2. Inspect and Replace Spark Plugs
  • Remove the ignition coil covers using a socket set.
  • Disconnect the ignition coils from the spark plugs.
  • Remove the old spark plugs using a spark plug socket.
  • Inspect the new spark plugs for proper gap (typically 0.044 inches for most applications).
  • Install new spark plugs and torque to manufacturer specifications (usually around 13-15 ft-lbs).
  • Reconnect the ignition coils and covers.
3. Clean or Replace MAF Sensor
  • Disconnect the MAF sensor electrical connector.
  • Remove the MAF sensor from the air intake duct.
  • If cleaning, use MAF cleaner and a soft brush; do not touch the sensor elements.
  • If replacement is necessary, install the new MAF sensor and reconnect the electrical connector.
4. Check for Vacuum Leaks
  • Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
  • Replace any damaged hoses as necessary.
  • Use a smoke machine or carburetor cleaner to check for leaks while the engine is running.
5. Final Assembly and Battery Reconnection
  • Reassemble any components removed for access (air intake duct, engine covers).
  • Reconnect the negative battery terminal.
  • Clear any error codes using the OBD-II scanner.
