Solution
1. Preparation
  • Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, safety glasses, gloves.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Inspect Fuel System
  • Fuel Filler Neck and Cap:
    • Remove the fuel cap and inspect for cracks or wear.
    • Replace if necessary.
  • Fuel Pressure Check:
    • Connect the fuel pressure gauge to the fuel rail.
    • Turn the ignition to the "ON" position (without starting) and check the pressure. It should be within the manufacturer's specified range (typically 30-50 psi).
    • If pressure is low, inspect the fuel pump and filter for issues.
3. Check EVAP System
  • Purge Valve and Charcoal Canister:
    • Locate the purge valve and disconnect the electrical connector.
    • Use a multimeter to test for proper function (check resistance).
    • Inspect the charcoal canister for cracks or blockages. Replace if needed.
4. Repair or Replace Faulty Components
  • Replace any damaged components identified in previous steps (fuel cap, purge valve, charcoal canister).
  • If spark plugs are worn, replace them following the manufacturer's specifications (typically torque to 13 lb-ft).
5. Reassemble and Test
  • Reconnect the battery and ensure all tools are removed from the engine bay.
  • Clear any diagnostic trouble codes and test drive the vehicle to ensure the rough idle has been resolved.
