Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install the new air filter, ensuring a snug fit.
Reattach the housing cover securely.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body using a screwdriver.
Spray throttle body cleaner onto a clean rag and gently wipe the throttle plate and body.
Ensure that no cleaner enters the intake manifold directly.
Reinstall the intake duct and tighten the clamps.

4. Replace Spark Plugs

Remove the ignition coil cover using the appropriate socket.
Unplug the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Install new spark plugs, torquing them to the manufacturer's specifications (typically about 13-15 lb-ft).
Reinstall the ignition coils and cover.

5. Check Fuel Filter and Lines

Locate the fuel filter and inspect for clogs or leaks.
Replace the fuel filter if it's clogged or has been in use beyond its service interval.
Inspect fuel lines for any signs of damage or leaks.
