Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, socket set, fuel pressure gauge.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting any work.

2. Address Engine Codes

Using the OBD-II scanner, retrieve and document any diagnostic trouble codes (DTCs).
Repair any identified issues (e.g., replace faulty sensors or components).

3. Tire Maintenance

Check and adjust tire pressures to the manufacturer-recommended levels.
Replace tires if tread depth is below the legal limit or manufacturer recommendations.

4. Air Filter Replacement

Locate the air filter housing and open it.
Remove the old air filter and install a new one according to the manufacturer’s specifications.
Ensure the housing is sealed correctly after replacement.

5. Fuel System Cleaning

Use a fuel system cleaner additive to clean fuel injectors, or remove injectors for professional ultrasonic cleaning.
If leaks are found, replace faulty fuel injectors as necessary.

6. Spark Plug Inspection/Replacement

Remove the spark plug wires and unscrew the spark plugs using a socket wrench.
Inspect for wear, carbon buildup, or damage; replace with new plugs if necessary, ensuring proper gap settings according to specifications.
