Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety when working on electrical components.

2. Replace Air Filter

Remove the air filter cover by unscrewing any screws or unclipping it.
Take out the old air filter and clean the housing with a vacuum or cloth.
Insert the new air filter, ensuring it fits snugly, then reattach the cover.
Tools Required: Flathead screwdriver, new air filter.

3. Replace Spark Plugs

Remove the ignition coil or spark plug wires carefully.
Use a socket wrench to unscrew the old spark plugs from the engine.
Check the gap on the new spark plugs and adjust if necessary.
Install the new spark plugs, tightening them to manufacturer specifications (typically 13-15 ft-lbs).
Reattach the ignition coil or spark plug wires.
Tools Required: Spark plug socket, torque wrench, gap tool.

4. Clean Fuel Injectors

If applicable, use a fuel injector cleaning kit or have them cleaned professionally.
If cleaning manually, remove the fuel rail and carefully remove the injectors.
Soak injectors in a cleaning solution and use compressed air to clean them thoroughly.
Reinstall injectors and ensure all connections are secure.
Tools Required: Fuel injector cleaning kit, safety goggles.
