Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the negative terminal of the battery to ensure safety while working on electrical components.
2. Fuel System Inspection
  • Fuel Pump Check
    • Use a fuel pressure gauge to check the fuel pump pressure against manufacturer specifications.
    • If pressure is low, replace the fuel pump.
  • Fuel Filter Replacement
    • Locate the fuel filter.
    • Disconnect the fuel lines (use caution as fuel may spray).
    • Remove the old filter and install a new one, ensuring proper orientation.
3. Ignition System Repair
  • Inspect Spark Plugs
    • Remove the spark plug wires and unscrew the spark plugs using a socket set.
    • Check for wear or fouling on the plugs; replace if necessary.
  • Test Ignition Coils
    • Use a multimeter to test the resistance of the ignition coils.
    • Replace any faulty coils.
4. Throttle Body Cleaning
  • Remove Throttle Body
    • Disconnect the air intake duct and other connected sensors or hoses.
    • Remove the throttle body mounting bolts and carefully detach it.
  • Clean Throttle Body
    • Use throttle body cleaner and a soft brush to clean any carbon buildup.
    • Reinstall the throttle body ensuring all gaskets are intact.
5. Final Assembly
  • Reconnect all components that were removed during inspection and repairs.
  • Reconnect the negative terminal of the battery.
