Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a screwdriver.
Take out the old air filter and inspect it for dirt or damage.
Replace with a new air filter if necessary.
Reassemble the air filter housing.

3. Clean or Replace Fuel Injectors

Use a fuel injector cleaner if they are dirty or perform a professional cleaning.
If injector replacement is needed:
- Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect the fuel lines and electrical connectors from the injectors.
- Remove old injectors and install new ones.
- Reconnect fuel lines and reconnect the fuel pump fuse.

4. Check and Adjust Tire Pressure

Use a tire gauge to check the pressure of all tires.
Inflate tires to the manufacturer’s recommended PSI.
Inspect tires for wear and replace them if necessary.

5. Inspect Exhaust System

Visually inspect the exhaust pipes for any visible leaks or damage.
Use a smoke test to identify any hidden leaks.
Repair or replace any damaged exhaust components.
