Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts while working.

2. Air Filter Replacement

Sub-steps:
1. Locate the air filter housing (typically on top of the engine).
2. Remove the screws or clips securing the air filter housing.
3. Remove the old air filter.
4. Install a new OEM air filter, ensuring a proper fit.
5. Reassemble the housing and secure screws or clips.

3. Fuel Injector Cleaning

Sub-steps:
1. Access the fuel rail by removing any engine covers if necessary.
2. Disconnect the fuel lines carefully using a fuel line disconnect tool.
3. Remove the fuel injectors from the fuel rail.
4. Clean each injector using a professional fuel injector cleaner or have them professionally cleaned.
5. Reinstall the cleaned or new injectors and reconnect fuel lines.

4. Tire Maintenance

Sub-steps:
1. Check tire pressure using a tire pressure gauge; inflate to manufacturer's recommended PSI.
2. Inspect tread depth using a tread depth gauge; replace tires if tread is worn.
3. Rotate tires if uneven wear is detected.

5. Exhaust System Inspection

Sub-steps:
1. Inspect the exhaust system from the engine to the tailpipe for any visible damage or rust.
2. Use a smoke test to detect leaks if visual inspection is inconclusive.
3. Repair or replace any damaged exhaust components.
