Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Disconnect the battery to ensure safety during the repair process.
2. Clean Throttle Body
  • Remove the air intake duct to access the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
  • Reassemble the air intake duct and ensure all connections are secure.
3. Inspect and Replace Idle Air Control Valve (if faulty)
  • Locate the idle air control valve on the throttle body or intake manifold.
  • Disconnect the electrical connector and remove the mounting screws.
  • Install the new idle air control valve and reconnect the electrical connector.
  • Torque the screws to manufacturer specifications (usually around 10 Nm).
4. Fuel System Inspection
  • Connect a fuel pressure gauge to the fuel rail to check for proper pressure (typically 3.5-4.5 bar for Clio).
  • If pressure is low, inspect the fuel pump and filter; replace if necessary.
  • Ensure fuel injectors are clean and functioning properly.
5. Reconnect Battery
  • Once all components have been addressed, reconnect the battery terminals.
