Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, basic hand tools.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspecting components.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve and note the trouble codes.
Research each code to determine specific issues and recommended repairs.

3. Inspect and Replace Faulty Components

Gas Cap: If the code indicates an evaporative emissions issue, inspect the gas cap. Replace if damaged or not sealing properly.
Spark Plugs:
- Remove the ignition coils using a socket set.
- Extract the spark plugs and inspect for wear or carbon buildup.
- Replace spark plugs with OEM parts, torquing to manufacturer specifications (typically around 13 lb-ft).
