Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.
Allow the engine to cool if it has been running.

2. Address Faulty Ignition Components

Sub-step 1: Remove engine cover (if applicable) using a socket set.
Sub-step 2: Disconnect ignition coil connectors and remove the ignition coils using a socket wrench.
Sub-step 3: Inspect spark plugs for damage or excessive wear; replace them if necessary (recommended gap: 0.028-0.031 inches).
Sub-step 4: Reinstall new or inspected ignition coils and secure them with the socket wrench.

3. Inspect Air Intake System

Sub-step 1: Remove the air intake duct by loosening hose clamps and disconnecting any sensors.
Sub-step 2: Inspect the air filter for dirt or blockages; replace if necessary.
Sub-step 3: Check for cracks or disconnections in the intake hoses and replace any damaged components.
Sub-step 4: Reassemble the air intake system, ensuring all connections are secure.

4. Test Fuel System

Sub-step 1: Connect a fuel pressure gauge to the fuel rail.
Sub-step 2: Turn on the ignition (do not start the engine) and check the pressure; it should meet specifications (typically around 43-50 psi for the XC60).
Sub-step 3: If pressure is low, check the fuel pump and filter for issues and replace if necessary.
