Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off and cool.
Disconnect the negative battery terminal for safety.

2. Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the filter housing.
Take out the old air filter and clean the housing with a vacuum.
Install a new air filter (ensure it meets specifications).
Re-secure the housing and reconnect the battery terminal.

3. Clean Fuel Injectors

Use a fuel injector cleaning kit compatible with your vehicle.
Follow the manufacturer’s instructions to connect the cleaning kit.
Run the engine as specified until the cleaning solution is used up.
Disconnect the cleaning kit and reconnect the fuel line.

4. Inspect and Repair Exhaust System

Visually inspect the exhaust pipes and muffler for signs of rust or holes.
If leaks are found, replace damaged sections or gaskets as necessary.
Ensure all connections are tight to prevent air leaks.

5. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire’s pressure.
Inflate tires to the manufacturer’s recommended PSI found in the driver’s door jamb.
Rotate or replace tires if tread is excessively worn.
