Solution

1. Preparation

• Tools Needed: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge.
• Disconnect the negative battery terminal to ensure safety.

2. Address Fuel System Issues

• a. Check Fuel Pump Operation:
  • Reconnect the battery and turn the ignition to the "ON" position without starting the engine. Listen for the fuel pump's operation.

  • Remove spark plugs using a socket set. Check for wear and carbon buildup. Replace if necessary with OEM-spec plugs.
• b. Test Ignition Coils:
  • Using a multimeter, check the resistance of each ignition coil. Replace any coils that do not meet specifications.

4. Clean the Throttle Body

• a. Remove Throttle Body:
  • Disconnect the throttle body wiring harness and remove the throttle body using a socket set.
• b. Clean:
  • Use throttle body cleaner and a soft brush to remove carbon deposits. Ensure all passages are clear.
