Solution

1. Preparation

Gather tools and materials needed for repairs.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while performing electrical inspections.

2. Air Filter Replacement

Sub-steps:
1. Locate the air filter housing and remove the screws or clips securing it.
2. Carefully lift the housing cover and remove the old air filter.
3. Install the new air filter, ensuring it fits snugly in place.
4. Reassemble the air filter housing and secure it with screws or clips.
Tools Required: Screwdriver
Safety Warnings: Ensure the engine is cool before starting.

3. Fuel Injector Cleaning/Replacement

Sub-steps:
1. Disconnect the fuel pump relay to relieve fuel pressure.
2. Remove the fuel rail to access the fuel injectors.
3. Clean the injectors using a specialized fuel injector cleaner or replace them if necessary.
4. Reinstall the fuel rail and reconnect all components securely.
Tools Required: Socket set, fuel injector cleaner (if cleaning), replacement injectors (if needed).
Safety Warnings: Disconnect the battery before working on fuel systems.

4. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check each tire's pressure.
2. Inflate or deflate tires to match the manufacturer's recommended pressure (found on the driver’s door jamb).
Tools Required: Tire pressure gauge, air compressor or tire inflator.
Safety Warnings: Ensure the vehicle is on a level surface and parked securely.
