Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, vacuum gauge
Perform a visual inspection of the engine bay for any obvious issues (wires, hoses, etc.).
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Ignition Components

Sub-steps:
1. Remove the engine cover (if applicable) using the socket set.
2. Disconnect the ignition coil connectors and remove the ignition coils.
3. Remove and inspect spark plugs for wear. Replace if necessary (use OEM specifications for parts).
4. Reinstall new spark plugs and ignition coils, ensuring proper torque specifications (typically around 15 Nm for spark plugs).
5. Reconnect the ignition coil connectors and engine cover.

3. Fuel System Inspection

Sub-steps:
1. Check fuel pressure using a fuel pressure gauge according to manufacturer specifications.
2. Inspect and clean or replace fuel injectors if clogged.
3. Ensure the fuel filter is not blocked and replace if necessary.

4. Check for Vacuum Leaks

Sub-steps:
1. Use a vacuum gauge to check the engine vacuum.
2. Inspect hoses for cracks or disconnections; replace any faulty hoses.
3. Use a smoke machine to identify any hidden leaks in the intake system.

5. Finalize Repairs

Sub-steps:
1. Reconnect the battery and clear any stored trouble codes using the OBD-II scanner.
2. Start the engine and allow it to idle for a few minutes to ensure proper operation.
