Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Retrieve Error Codes

Using the OBD-II scanner, connect to the vehicle's diagnostic port.
Record any error codes and descriptions for further analysis.
Clear the codes if necessary to see if they reappear after a test drive.

3. Inspect Ignition System

Remove the engine cover if applicable.
Check spark plugs for wear or fouling; replace if necessary with OEM parts.
Test ignition coils for proper resistance using a multimeter; replace any faulty coils.

4. Check for Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner to locate leaks around the intake manifold.
Replace any damaged hoses or gaskets identified during the inspection.

5. Examine the Fuel System

Check fuel pressure using a fuel pressure gauge, ensuring it meets manufacturer specifications.
Inspect the fuel filter and replace if clogged or dirty.
Ensure the fuel injectors are clean and functioning properly; clean or replace as needed.

6. Verify Engine Oil Condition

Check the engine oil level using the dipstick; top off or replace oil if necessary.
Inspect the oil condition; if it appears contaminated, perform an oil change using the recommended oil type.

7. Inspect Exhaust System

Check exhaust pipes and the catalytic converter for blockages or damage.
Repair or replace any damaged components to ensure proper exhaust flow.
