Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, fuel pressure gauge, vacuum gauge, multimeter.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery before beginning work on electrical components.
2. Address Fault Codes
  • Use the OBD-II scanner to read and document any error codes.
  • Clear the codes and perform a test drive to see if they return, which may help in pinpointing the issue.
3. Replace Air Filter
  • Locate the air filter housing and remove it by unscrewing or unclipping.
  • Replace the old air filter with a new one, ensuring it fits snugly.
  • Reassemble the housing and secure it properly.
4. Inspect and Test Fuel System
  • Connect a fuel pressure gauge to the fuel rail to check for correct pressure specifications (usually around 3-4 bar for most Renault models).
  • If pressure is low, check the fuel pump and filter for clogs or failure.
  • Replace the fuel filter if necessary.
5. Repair or Replace Faulty Components
  • Inspect the ignition system; replace spark plugs if they show signs of wear or fouling.
  • Check ignition coils with a multimeter; replace if they do not meet manufacturer specifications.
  • If the idle air control valve is faulty, remove it and clean it with throttle body cleaner, or replace it if necessary.
6. Reconnect Battery and Test
  • Once repairs are complete, reconnect the battery.
  • Start the engine and allow it to reach operating temperature while observing idle stability.
