Solution
1. Preparation
  • Gather tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Replace Faulty Spark Plugs and Ignition Coils
  • Tools Required: Socket set, torque wrench.
  • Remove any engine covers if necessary.
  • Use a spark plug socket to unscrew and remove the old spark plugs.
  • Inspect ignition coils; if any are cracked or damaged, replace them.
  • Install new spark plugs, ensuring to torque them to the manufacturer's specifications (typically 15-20 lb-ft).
  • Reattach ignition coils.
3. Address Vacuum Leaks
  • Tools Required: Vacuum gauge, hose clamp pliers.
  • Locate and inspect all vacuum hoses for cracks or disconnections.
  • Replace any damaged hoses and secure them with proper clamps.
  • Use a vacuum gauge to check for proper readings; if low, consider further inspection or replacement of the intake manifold gasket.
4. Replace Air Filter
  • Tools Required: None specifically, but may use a screwdriver if clamps are present.
  • Open the air intake housing and remove the old air filter.
  • Install the new air filter, ensuring it fits snugly in place.
5. Reconnect Battery and Clear Codes
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear any stored error codes.
  • Start the engine and observe for any recurring issues.
