Solution

1. Tire Maintenance

Sub-steps:
- Use a tire pressure gauge to check all tires.
- Inflate tires to the recommended PSI found in the owner’s manual or on the driver’s door jamb.
- Rotate tires every 5,000 miles to ensure even wear.

2. Air Filter Replacement

Sub-steps:
- Locate the air filter housing (typically near the engine).
- Open the housing by unclipping or unscrewing it.
- Remove the old air filter and clean the housing with a soft cloth.
- Install the new air filter, ensuring proper fitment and sealing.

3. Fuel Injector Cleaning

Sub-steps:
- Purchase a fuel injector cleaning kit or use a professional service.
- If DIY, connect the cleaning kit to the fuel rail following manufacturer's instructions.
- Run the engine as directed to allow the cleaning solution to flush through the injectors.

4. Spark Plug Inspection and Replacement

Sub-steps:
- Remove the engine cover if applicable, using a socket set.
- Disconnect the ignition coils and remove them.
- Use a spark plug socket to remove old spark plugs.
- Inspect for wear and replace with OEM or equivalent spark plugs, ensuring proper torque (typically around 15 lb-ft).
- Reconnect ignition coils and replace the engine cover.

5. Emissions System Check

Sub-steps:
- Inspect the exhaust system visually for any signs of damage or leaks.
- Use a multimeter to test O2 sensors for proper function.
- Replace any faulty components as necessary.
