Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, basic hand tools (sockets, wrenches), air filter wrench, fuel injector cleaner.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery if necessary.

2. Tire Maintenance

Sub-steps:
1. Use a tire pressure gauge to check the pressure of all four tires.
2. Inflate tires to the recommended pressure found on the driver’s door jamb.
3. Inspect tread depth and condition; replace tires if worn out.

3. Air Filter Replacement

Sub-steps:
1. Open the hood and locate the air filter housing.
2. Remove the screws or clips securing the housing and take off the cover.
3. Remove the old air filter and replace it with a new one, ensuring a snug fit.
4. Reassemble the air filter housing and secure it properly.

4. Fuel System Maintenance

Sub-steps:
1. Add a fuel injector cleaner to a full tank of gasoline according to the product instructions.
2. Drive the vehicle for a few hundred miles to allow the cleaner to circulate through the fuel system.
3. If necessary, inspect and clean the fuel injectors using specialized cleaning equipment.

5. Sensor Inspection

Sub-steps:
1. Locate the mass airflow sensor (MAF) and throttle position sensor (TPS).
2. Disconnect the electrical connectors carefully.
3. Clean the MAF sensor with MAF cleaner and inspect the TPS for wear.
4. Reconnect the sensors ensuring secure connections.

6. Exhaust System Check

Sub-steps:
1. Visually inspect the exhaust system for signs of leaks or damage.
2. Use a smoke test or pressure test to identify any blockages.
3. Repair or replace any damaged components as necessary.
