Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's OBD-II port.
Turn the ignition to the "On" position without starting the engine.
Record any trouble codes displayed and refer to a repair manual for their meanings.

3. Inspect the Ignition System

Remove the engine cover if necessary.
Check spark plugs for wear or damage; replace if needed.
Test ignition coils with a multimeter for proper resistance; replace faulty coils.

4. Check Fuel System

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position and check for adequate fuel pressure.
Inspect fuel injectors for leaks or clogs; clean or replace as necessary.

5. Examine for Vacuum Leaks

Start the engine and listen for hissing sounds around hoses and intake manifold.
Use a smoke machine or carb cleaner to detect leaks; repair or replace damaged hoses.

6. Review Exhaust System

Inspect exhaust pipes, catalytic converter, and muffler for blockages or damage.
Use a vacuum gauge to check for back pressure; replace components as needed.
