Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery before working on electrical systems.
Ensure the vehicle is on a flat surface and secure with wheel chocks.

2. Diagnose and Replace Ignition Components

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Disconnect the ignition coils and remove them using a socket set.
3. Inspect spark plugs for wear or damage; replace if necessary.
4. Install new ignition coils and reconnect electrical connectors.
5. Torque bolts to manufacturer specifications (typically 8-12 ft-lbs).

3. Inspect and Clean Fuel Injectors

Sub-steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
2. Disconnect fuel lines from the injectors (use caution).
3. Remove the fuel injectors from the intake manifold.
4. Clean injectors using a specialized fuel injector cleaning kit.
5. Reinstall cleaned or new injectors and reconnect fuel lines.

4. Check for Vacuum Leaks

Sub-steps:
1. Start the engine and use a smoke machine or propane torch to check for vacuum leaks around hoses and gaskets.
2. Replace any damaged vacuum hoses or gaskets found during inspection.

5. Final Assembly

Sub-steps:
1. Reattach any components removed during diagnostics and repairs.
2. Reconnect the battery.
3. Clear any error codes using the OBD-II scanner.
