Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.
Allow the engine to cool if it has been running.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and visually inspect it for dirt and damage.
Install a new air filter (ensure it is the correct size for the XC60).
Reattach the air filter housing cover and tighten it securely.

3. Fuel System Check

Locate the fuel pump relay and remove it.
Test the fuel pump operation using a fuel pressure gauge to verify that it is providing adequate pressure (should be around 60-70 psi for the XC60).
If pressure is low, replace the fuel pump and filter.
Reinstall the fuel pump relay.

4. Clean Throttle Body

Remove the intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Ensure the throttle plate moves freely and reattach the intake duct securely.

5. Transmission Fluid Inspection

Locate the transmission dipstick (if applicable) and check the fluid level.
If low or discolored, drain the old transmission fluid and replace it with new fluid according to the manufacturer’s specifications.
Reinsert the dipstick and check the level again.
