Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, vacuum gauge, throttle body cleaner, safety glasses, gloves.
  • Ensure the vehicle is parked on a level surface and the engine is turned off before beginning repairs.
2. Address Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Retrieve and document any error codes that may indicate the source of the rough idle.
  • Clear the codes after noting them for further reference.
3. Inspect Air Intake System
  • Remove the air intake duct to access the throttle body.
  • Visually inspect for any signs of cracks or disconnections in the ductwork.
  • Clean any debris or obstructions found in the air filter or intake area.
4. Check Fuel System
  • Use a fuel pressure gauge to measure the fuel pressure at the fuel rail.
  • Replace the fuel filter if it shows signs of clogging.
  • If fuel pressure is low, inspect the fuel pump and related components.
5. Examine Ignition System
  • Remove the spark plugs using a socket wrench and inspect them for wear, carbon deposits, or damage.
  • Replace any faulty spark plugs and ensure they are torqued to manufacturer specifications (typically around 15-20 Nm).
  • Check the ignition wires for signs of wear or damage.
6. Inspect and Clean Throttle Body
  • Remove the throttle body from the intake manifold if significant carbon buildup is present.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
  • Reinstall the throttle body, ensuring all gaskets are replaced and torqued to specifications.
