Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Ensure the vehicle is on a flat surface and secured with wheel chocks.

2. Replace Air Filter

Remove the air filter housing cover using a screwdriver.
Take out the old air filter and inspect it; replace if dirty.
Install the new air filter, ensuring it fits snugly in place.
Reattach the air filter housing cover and secure with screws.

3. Clean or Replace Fuel Injectors

If cleaning, use a fuel injector cleaning kit; follow the manufacturer's instructions.
If replacing, disconnect the fuel lines and remove the fuel rail.
Take out the old injectors and install new ones, ensuring O-rings are lubricated.
Reassemble the fuel rail and reconnect fuel lines; check for leaks.

4. Check and Inflate Tires

Use a tire pressure gauge to measure tire pressure.
Inflate tires to the recommended PSI as indicated on the door jamb.
Inspect tire tread for wear and replace if necessary.

5. Repair or Replace Exhaust System Components

Inspect exhaust pipes, mufflers, and catalytic converters for damage or leaks.
Replace any damaged components with OEM or equivalent parts.
Ensure all connections are tight and free from leaks.
