Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, multimeter, fuel injector cleaner, replacement spark plugs (if needed).
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "on" position without starting the engine.
Retrieve and record any error codes related to fuel system, air intake, or misfires.

3. Inspect Air Filter

Open the hood and locate the air filter housing.
Remove the air filter and inspect for dirt and debris.
Replace with a new air filter if it appears clogged.

4. Check Fuel Injectors

Remove the fuel rail cover if applicable.
Inspect fuel injectors for signs of leakage.
Use fuel injector cleaner to clean the injectors or replace them if they are faulty.

5. Inspect Spark Plugs

Remove spark plug wires or ignition coils as needed.
Extract spark plugs using a socket wrench.
Inspect spark plugs for wear or fouling; replace if necessary with OEM specified parts.

6. Exhaust System Inspection

Visually check the exhaust system for leaks or blockages.
If any issues are found, repair or replace the affected components.
