Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge, basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Address Ignition System Issues

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Inspect each spark plug for wear; replace if necessary (use OEM parts).
3. Check ignition coils for proper operation using a multimeter; replace faulty coils.
4. Reinstall the engine cover.

3. Inspect Fuel System

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position (do not start the engine) and check pressure against specifications (typically around 50-60 psi for XC60).
3. If pressure is low, check the fuel filter and pump; replace as necessary.
4. If the fuel system is functioning correctly, reconnect the fuel line.

4. Check Air Intake System

Sub-steps:
1. Remove the air intake duct.
2. Inspect the air filter for clogging; replace if dirty.
3. Check for any air leaks in the intake manifold or throttle body.
4. Clean the throttle body with a throttle body cleaner if necessary.

5. Examine Vacuum Lines

Sub-steps:
1. Visually inspect all vacuum lines for cracks or disconnections.
2. Replace any damaged lines with OEM replacements.
3. Recheck connections to ensure they are secure.

6. Test Drive

After repairs, reconnect the negative battery terminal and start the engine.
Monitor for any warning lights and perform a test drive to verify the fix.
