Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

Tools Required: Screwdriver or socket set
Remove the air filter housing cover by unscrewing or unclipping it.
Take out the old air filter and replace it with a new one, ensuring it fits snugly.
Reattach the housing cover and secure it.

3. Clean or Replace Fuel Injectors

Tools Required: Fuel injector cleaning kit or replacement injectors
Disconnect the fuel lines and electrical connectors from the injectors.
If cleaning, use a fuel injector cleaning kit to flush out any obstructions.
If replacing, remove the old injectors and install new ones, ensuring O-rings are lubricated for a proper seal.

4. Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench
Remove the ignition coils or spark plug wires to access the spark plugs.
Unscrew and remove the old spark plugs.
Install new spark plugs, tightening them to the manufacturer's specified torque (typically around 15-20 lb-ft).
Reconnect the ignition coils or spark plug wires.

5. Check and Repair Exhaust System

Tools Required: Wrenches, exhaust clamps, or welding kit if needed
Inspect the exhaust system for any visible leaks or damage.
Repair or replace any damaged sections, ensuring all connections are tight and sealed.
