Solution
1. Preparation
  • Gather tools and parts.
  • Disconnect the battery to prevent electrical shorts.
  • Allow the engine to cool down before starting work.
2. Replace Spark Plugs
  • Remove the engine cover if applicable.
  • Use a socket wrench to remove the ignition coil bolts.
  • Carefully detach the ignition coils from the spark plugs.
  • Use a spark plug socket to remove the old spark plugs.
  • Install new spark plugs to manufacturer specifications (typically 13-15 ft-lbs torque).
  • Reattach the ignition coils and secure them with bolts.
3. Test Ignition Coils
  • Use a multimeter to measure the primary and secondary resistance of each ignition coil.
  • If any coils are out of specification, replace them with new ones.
  • Reinstall ignition coils and secure properly.
4. Inspect Fuel System
  • Connect a fuel pressure gauge to the fuel rail.
  • Start the engine and check if the fuel pressure meets the manufacturer's specifications.
  • If pressure is low, inspect the fuel pump and fuel filter for issues.
5. Check for Vacuum Leaks
  • Visually inspect all vacuum hoses and the intake manifold.
  • Use a smoke machine or carburetor cleaner to detect leaks.
  • Replace or repair any damaged hoses or gaskets.
