Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical short circuits.

2. Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the air filter cover.
Take out the old air filter and check for dirt or debris.
Insert a new air filter, ensuring it fits snugly.
Reattach the air filter cover and secure it.

3. Clean Fuel Injectors

Remove the fuel injector rail by disconnecting the fuel lines (use a rag to catch any fuel spills) and unscrewing mounting bolts.
Use a fuel injector cleaner or ultrasonic cleaner to clean the injectors thoroughly.
Reinstall the cleaned injectors with new O-rings if necessary, ensuring a proper seal.

4. Replace Spark Plugs

Remove the ignition coils by unscrewing them from the engine.
Using a spark plug socket, remove the old spark plugs.
Check the gap on the new spark plugs and adjust if necessary.
Install the new spark plugs and torque them to the manufacturer's specifications.
Reattach the ignition coils.

5. Check and Adjust Tire Pressure

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate the tires to match the recommended specifications found on the driver's door jamb label.
