Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety when working on electrical components.

2. Address Engine Codes

Use the OBD-II scanner to retrieve and record error codes.
If codes indicate a specific issue (e.g., faulty oxygen sensor or mass airflow sensor), proceed with replacement.

3. Inspect and Replace Air Filter

Locate the air intake box and open it.
Remove the air filter and inspect for dirt or damage.
Replace with a new air filter if necessary.

4. Check and Clean Fuel Injectors

Remove the fuel rail to access the injectors.
Inspect for any signs of clogging or leaks.
Clean injectors using a fuel injector cleaning kit or replace if damaged.

5. Verify Tire Pressure and Alignment

Check tire pressures using a tire pressure gauge; inflate to manufacturer specifications.
Inspect alignment and adjust if necessary to ensure even tire wear.

6. Inspect Exhaust System

Visually inspect the exhaust manifold, catalytic converter, and muffler for leaks or blockages.
Repair or replace any damaged components.
