Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to avoid electrical hazards.

2. Address Error Codes

Connect the OBD-II scanner and retrieve error codes.
Document the codes for reference and research potential solutions based on the specific codes.

3. Inspect and Replace Spark Plugs

Remove the ignition coil cover if applicable.
Take out the spark plugs using a spark plug socket.
Inspect the plugs for wear; replace if they show signs of corrosion or damage.
Torque the new spark plugs to the manufacturer’s specifications (usually around 13-16 lb-ft).

4. Check Fuel System

Inspect the fuel injectors for clogs or leaks; clean or replace as necessary.
Replace the fuel filter if it is clogged or has not been changed in accordance with the maintenance schedule.

5. Test for Vacuum Leaks

Visually inspect all vacuum hoses and connections for cracks or disconnections.
Use a smoke machine or carburetor cleaner to identify any leaks; repair or replace faulty hoses.

6. Catalytic Converter Inspection

Examine the catalytic converter for any signs of damage or blockage.
If issues are detected, replace the catalytic converter according to the vehicle's specifications.
