Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Allow the engine to cool before starting any work.

2. Air Filter Replacement

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt or damage.
Replace with a new air filter and reassemble the housing cover, ensuring it is tightly secured.

3. Fuel System Inspection

Locate the fuel pressure test port on the fuel rail.
Connect a fuel pressure gauge to the port and turn the ignition to the "on" position without starting the engine to check the pressure.
If pressure is below specifications, inspect the fuel pump and fuel filter for blockages or failure. Replace components as needed.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold by disconnecting the electrical connector and loosening the mounting bolts.
Clean the throttle body using throttle body cleaner and a soft brush, focusing on the valve and surrounding areas.
Reinstall the throttle body, ensuring proper torque on the bolts to manufacturer specifications.

5. Ignition System Check

Remove the spark plugs using a spark plug socket and inspect for wear or deposits.
Replace any worn or fouled spark plugs with the correct specifications for the XC60.
Test ignition coils for proper resistance using a multimeter; replace any faulty coils.

6. Transmission Fluid Check

Locate the transmission dipstick and check fluid level; add the correct type of transmission fluid if low.
If the fluid appears dark or has a burnt smell, consider changing the fluid and filter according to manufacturer recommendations.
