why does my Volvo XC60 Second Generation (2018-2024) have a sluggish response when accelerating?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the battery to ensure safety.
• Allow the engine to cool down before starting work.

2. Clean or Replace Air Filter

• Locate the air filter housing.
• Open the housing and remove the air filter.
• Inspect the filter; if excessively dirty, replace it with a new one.
• Reassemble the air filter housing securely.

3. Inspect and Clean Throttle Body

• Remove the intake duct from the throttle body.
• Use a throttle body cleaner and a soft cloth to clean the throttle plate and housing.
• Ensure the throttle plate moves freely without obstruction.
• Reassemble the intake duct.

4. Test and Replace Spark Plugs

• Remove the ignition coils or spark plug wires as needed.
• Use a spark plug socket to remove the spark plugs.
• Inspect each spark plug for wear; replace if necessary with OEM specifications.
• Reinstall the spark plugs and ignition components.

5. Check Fuel System

• Connect a fuel pressure gauge to the fuel rail test port.
• Start the engine and observe the fuel pressure reading; compare with manufacturer specifications.
• If pressure is low, check for a clogged fuel filter or failing fuel pump.
• Replace fuel filter if applicable; consider fuel pump replacement if necessary.

6. Inspect Transmission Fluid

• Locate the transmission dipstick (if equipped).
• Check the fluid level and condition; it should be clean and reddish in color.
• If low or burnt, perform a transmission fluid change according to the manufacturer's specifications.
