Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's battery to prevent any electrical short circuits.
Ensure the engine is cool before starting work.

2. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Take out the old spark plugs using a spark plug socket and inspect for wear.
Replace with new spark plugs that meet manufacturer's specifications (typically NGK or Volvo OEM).
Torque the new spark plugs to the recommended specification (usually around 22 lb-ft).

3. Clean or Replace the Throttle Body

Remove the air intake duct to access the throttle body.
Disconnect the throttle body connector and remove the mounting bolts.
Clean the throttle body using throttle body cleaner and a soft cloth, removing any carbon deposits.
Reinstall the throttle body and reconnect the electrical connector.

4. Check and Clean the Mass Airflow Sensor

Locate the MAF sensor in the air intake duct.
Disconnect the electrical connector and remove the sensor.
Clean the MAF sensor using MAF cleaner spray (do not touch the sensor directly).
Reinstall the sensor and ensure it is properly connected.

5. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail test port.
Start the engine and check the fuel pressure; it should match manufacturer specifications (usually around 50-60 psi).
If pressure is low, inspect the fuel filter and fuel pump for blockages or wear, replacing them if necessary.
