Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical hazards.

2. Address Error Codes

Tools Required: OBD-II scanner
Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostic port.
2. Retrieve and record any error codes.
3. Research the codes to determine the specific issue.

3. Inspect and Replace Spark Plugs and Ignition Coils

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the engine cover (if applicable) to access spark plugs and ignition coils.
2. Disconnect the ignition coil connectors and remove the coils.
3. Remove the spark plugs using a socket wrench.
4. Inspect plugs for wear; replace with OEM spark plugs if necessary.
5. Reinstall ignition coils and connectors, ensuring they are seated properly.
6. Torque the spark plugs to the manufacturer's specifications (typically 13 lb-ft).

4. Fuel System Inspection

Tools Required: Fuel pressure gauge
Sub-steps:
1. Locate the fuel rail and connect the fuel pressure gauge.
2. Turn the ignition on (do not start the engine) and check pressure readings.
3. If pressure is low, inspect the fuel pump and filter for issues.
4. Replace fuel injectors if leaking or clogged.

5. Vacuum System Check

Tools Required: Smoke machine (optional)
Sub-steps:
1. Visually inspect vacuum hoses for cracks or disconnections.
2. If available, use a smoke machine to identify hidden vacuum leaks.
3. Replace any damaged hoses or components.
