Solution

1. Preparation

Gather tools and materials.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Air Filter

Locate the air filter housing in the engine compartment.
Open the housing by unclipping or unscrewing it.
Remove the old air filter and clean the housing.
Install a new air filter, ensuring it is seated correctly.
Reassemble the housing and reconnect any clips or screws.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the ON position (do not start the engine) to check for proper fuel pressure.
If pressure is low, inspect the fuel pump and replace if necessary.
Check fuel injectors for clogs; clean or replace as needed.

4. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wire to access the spark plug.
Use a spark plug socket to remove the spark plug and inspect for wear or damage.
Replace with new spark plugs that meet manufacturer specifications.
Reinstall the ignition coil or spark plug wire.

5. Throttle Body Cleaning

Locate the throttle body; disconnect the intake duct.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reassemble the intake duct securely.

6. Vacuum Leak Inspection

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke tester to identify any leaks in the intake manifold.
Replace any damaged hoses or reseal the intake manifold as necessary.
