Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before starting work.

2. Resolve Diagnostic Codes

If any trouble codes are present, address the specific faults indicated by the OBD-II scanner.
Clear the codes and retest the vehicle to confirm resolution.

3. Air Intake Inspection

Remove the air intake duct to access the throttle body.
Clean the throttle body using throttle body cleaner and a soft cloth.
Inspect the air filter and replace if dirty or clogged.

4. Fuel System Check

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (without starting) to check the fuel pressure reading; it should meet manufacturer specifications.
If pressure is low, replace the fuel filter, and check the fuel pump operation.

5. Ignition System Replacement

Remove the engine cover if applicable to access ignition components.
Replace spark plugs if they show signs of wear (gap may be outside specifications).
Test and replace any faulty ignition coils as needed.

6. Exhaust System Inspection

Inspect the exhaust system for any visible damage or leaks.
Check the catalytic converter for signs of blockage or overheating.
If the catalytic converter is damaged, replacement will be necessary.
