Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and is turned off.
• Disconnect the battery before working on electrical components.

2. Air Filter Replacement

• Remove the air filter housing cover using a socket set.
• Take out the old air filter and clean the housing.
• Insert the new air filter, ensuring it fits snugly.
• Reattach the housing cover and tighten screws to manufacturer specifications.

3. Fuel Injector Cleaning

• Use a fuel injector cleaning kit.
• Connect the kit to the fuel rail following the manufacturer’s instructions.
• Start the engine and run it as recommended in the cleaning kit instructions.
• Disconnect the kit and reconnect the fuel line.

4. Tire Pressure Adjustment

• Use a tire pressure gauge to check each tire’s pressure.
• Inflate tires to the recommended pressure stated on the driver’s door jamb sticker.
• Inspect tire tread for wear and replace if necessary.

5. Exhaust System Inspection

• Visually inspect the exhaust system for any signs of rust, holes, or leaks.
• If leaks are found, repair or replace the affected sections using exhaust sealant or clamps.
