Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean the Throttle Body

Remove the throttle body by unscrewing the bolts and disconnecting the electrical connector.
Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon deposits.
Reinstall the throttle body and torque the bolts to the manufacturer’s specifications (usually around 8-10 Nm).

3. Replace the Air Filter

Locate the air filter housing and unclip or unscrew it to access the air filter.
Remove the old air filter and install a new one, ensuring it fits snugly.
Reassemble the housing securely.

4. Test and Replace the Fuel Pump (if necessary)

Use a fuel pressure gauge to check the fuel pressure against manufacturer specifications (typically around 3-4 bar).
If pressure is low, disconnect the fuel lines and electrical connectors from the fuel pump.
Remove the fuel pump assembly from the tank and replace it with a new pump, ensuring proper sealing during installation.

5. Inspect and Replace the Mass Air Flow (MAF) Sensor (if necessary)

Locate the MAF sensor in the air intake duct and disconnect the electrical connector.
Remove the sensor from the duct and clean it with MAF sensor cleaner.
If cleaning does not resolve issues, replace the sensor with a new one.
