Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

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 a new air filter, ensuring it fits snugly.
Reattach the air filter housing cover securely.

3. Test and Replace Spark Plugs

Remove the ignition coil from the spark plug using a socket wrench.
Extract the spark plug using a spark plug socket and inspect for wear or carbon deposits.
Replace with new spark plugs, tightening them to the manufacturer's torque specifications (typically 13-15 lb-ft).
Reinstall the ignition coil.

4. Check and Replace Ignition Coils (if necessary)

Disconnect the electrical connector from the ignition coil.
Remove the ignition coil using a socket set.
Install the new ignition coil and reconnect the electrical connector.

5. Inspect and Repair Vacuum Leaks

Visually inspect all vacuum hoses and the intake manifold for cracks or loose connections.
Replace any damaged hoses and ensure all connections are tight.
