Solution
1. Preparation
  • Gather tools and parts needed for repair.
  • Disconnect the negative battery terminal to ensure safety during repairs.
2. Address Fuel System Issues
  1. Inspect the Fuel Pump:
    • Remove the fuel pump access cover.
    • Check the fuel pump operation by turning the ignition to the "ON" position (do not start) and listen for the pump's operation.
    • If not functioning, replace the fuel pump.
  2. Replace the Fuel Filter:
    • Relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.
    • Disconnect the fuel lines from the fuel filter using a line wrench.
    • Replace the old fuel filter with a new one and reconnect the lines securely.
3. Repair Ignition System
  1. Inspect and Replace Spark Plugs:
    • Remove the ignition coil cover (if applicable).
    • Use a spark plug socket to remove the spark plugs.
    • Inspect for wear and replace with manufacturer-recommended spark plugs.
  2. Check Ignition Coils:
    • Test each ignition coil using a multimeter for resistance.
    • Replace any faulty coils.
4. Clean Throttle Body
  1. Remove the Throttle Body:
    • Disconnect the electrical connectors and throttle body bolts.
    • Carefully remove the throttle body from the intake manifold.
  2. Clean the Throttle Body:
    • Use throttle body cleaner and a soft cloth to remove carbon deposits.
    • Reinstall the throttle body and reconnect all components.
5. Inspect and Repair Vacuum Leaks
  1. Visual Inspection:
    • Check all vacuum lines for cracks or disconnections.
    • Replace any damaged lines.
  2. Smoke Test:
    • If necessary, perform a smoke test to identify hard-to-find leaks.
