why does my Renault Clio V suddenly lose acceleration

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Disconnect the battery to prevent any electrical shorts.

2. Throttle Body Cleaning

• Remove the air intake duct connected to the throttle body.
• Use a throttle body cleaner and a soft cloth to clean carbon deposits from the throttle plate and surrounding area.
• Reassemble the air intake duct securely.

3. Fuel System Check

• If fuel pressure is low, replace the fuel filter and inspect the fuel pump for proper operation.
• Disconnect the fuel line at the fuel filter and check for any blockages.
• Reconnect the fuel line and prime the fuel system before starting the engine.

4. MAF Sensor Inspection

• Disconnect the MAF sensor connector.
• Use a multimeter to test the sensor's voltage output per manufacturer specifications.
• Clean the MAF sensor with MAF cleaner if it appears dirty; otherwise, replace it if faulty.

5. Ignition System Replacement

• Remove the spark plugs using a socket wrench.
• Inspect the spark plugs for signs of wear or fouling; replace them if necessary.
• Test or replace the ignition coils as required.
