Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to avoid any electrical issues during repair.

2. Inspect and Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing cover.
Take out the old air filter and inspect it for dirt or damage.
Install a new air filter, ensuring it fits snugly.
Reattach the housing cover and secure it properly.

3. Check and Clean Fuel Injectors

Remove the engine cover if applicable.
Disconnect the fuel lines from the injectors (ensure to relieve fuel pressure first).
Remove the injectors from the intake manifold.
Use a fuel injector cleaning kit to clean the injectors thoroughly.
Reinstall the cleaned or new injectors, ensuring O-rings are intact and properly seated.
Reattach fuel lines and check for leaks.

4. Inspect Fuel System for Leaks

Visually inspect the fuel lines and connections for signs of wear or leaks.
Use a fuel pressure gauge to check if the fuel pump is delivering the correct pressure.
If leaks are found, replace the damaged sections of fuel line or fittings.

5. Tire Inspection and Adjustment

Check tire pressure using a tire gauge; inflate to manufacturer's recommended levels.
Inspect tire tread for uneven wear, which may indicate alignment issues.
Rotate or replace tires if necessary.
