Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery to prevent electrical short circuits.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the existing air filter and inspect for dirt and blockages.
Replace with a new, clean air filter (ensure it is the correct size for the Clio V).
Reassemble the air filter housing and secure the cover.

3. Test and Replace Throttle Position Sensor (if necessary)

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the sensor using a socket set.
Install the new throttle position sensor and reconnect the electrical connector.
Ensure the sensor is properly aligned and secured.

4. Inspect and Replace Spark Plugs

Remove the ignition coil(s) or spark plug wires carefully.
Use a spark plug socket to remove the spark plugs.
Inspect the spark plugs for wear, deposits, or damage.
Replace with new spark plugs as per manufacturer specifications (check gap settings).
Reinstall the ignition coil(s) or spark plug wires.

5. Check and Replace Fuel Pump (if necessary)

Access the fuel pump through the rear seat or trunk (depending on the design).
Disconnect the fuel lines and electrical connector.
Remove the fuel pump assembly and inspect for damage.
Install a new fuel pump assembly, ensuring all connections are secure and leak-free.
