Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shock.
2. Address Fuel System Issues
  • Inspect the Fuel Pump:
    • Remove the rear seat cushion to access the fuel pump.
    • Use a multimeter to test the fuel pump’s voltage while the ignition is in the ON position.
    • If there is no voltage, check the fuel pump relay and associated wiring.
  • Replace the Fuel Filter:
    • Locate the fuel filter and relieve fuel system pressure.
    • Disconnect the fuel lines using a fuel line disconnect tool.
    • Replace the old filter with a new one, ensuring correct orientation.
3. Check Ignition System
  • Inspect Spark Plugs:
    • Remove the spark plug wires and unscrew the spark plugs using a socket wrench.
    • Inspect for wear or carbon buildup; replace if necessary with OEM specifications.
  • Test Ignition Coils:
    • Use a multimeter to check the resistance of each ignition coil.
    • Replace any coils that are out of specification.
4. Clean Throttle Body
  • Remove Throttle Body:
    • Disconnect the air intake hose and electrical connectors.
    • Unbolt the throttle body from the intake manifold.
  • Clean Throttle Body:
    • Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
    • Reinstall the throttle body, ensuring proper torque specifications.
5. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Start the engine and let it idle to check for any irregularities.
