Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, basic hand tools (sockets, wrenches), new air filter, fuel injector cleaner.
Safety Warnings: Ensure the vehicle is on a flat surface and the engine is off before beginning work.

2. Tire Pressure Adjustment

Sub-steps:
1. Remove the valve cap from each tire.
2. Use the tire pressure gauge to measure the current pressure.
3. Inflate tires to the recommended PSI found in the owner's manual or on the driver’s side door jamb.
4. Replace valve caps securely.

3. Engine Diagnostics

Sub-steps:
1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
2. Retrieve and note any diagnostic trouble codes (DTCs).
3. Clear codes and see if they return after a short drive.

4. Air Filter Replacement

Sub-steps:
1. Locate the air filter housing (typically near the engine).
2. Open the housing by unscrewing or unclipping it.
3. Remove the old air filter and inspect it for dirt and damage.
4. Install a new air filter, ensuring it fits snugly and securely close the housing.

5. Fuel Injector Cleaning

Sub-steps:
1. Purchase a fuel injector cleaning kit or cleaner.
2. Follow the product instructions to add the cleaner to the fuel tank.
3. Run the vehicle to circulate the cleaner through the fuel system.

6. Oil Change (if necessary)

Sub-steps:
1. Gather necessary tools: oil filter wrench, oil catch pan, new oil filter, and appropriate engine oil.
2. Lift the vehicle safely using jack stands.
3. Drain the old oil into the catch pan and replace the oil filter.
4. Refill with new oil as specified in the owner’s manual.
