Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cold.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace Air Filter

Open the hood and locate the air filter housing.
Remove the clips or screws holding the housing cover and lift it off.
Take out the old air filter and inspect it for dirt or damage.
Replace with a new air filter that meets OEM specifications.
Reassemble the housing cover and secure it properly.

3. Clean Throttle Body

Remove the throttle body from the intake manifold by loosening the bolts.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Ensure no cleaner enters the intake manifold.
Reinstall the throttle body and torque the bolts to manufacturer specifications.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers (if applicable) to access the spark plugs.
Use a spark plug socket and ratchet to remove each spark plug.
Inspect plugs for wear, carbon buildup, or damage and replace if necessary with OEM parts.
Reinstall coils and covers, ensuring they are seated correctly.

5. Check and Replace Fuel Filter (if applicable)

Follow the fuel lines to locate the fuel filter.
Relieve fuel system pressure before removal.
Disconnect the fuel lines from the filter and remove it.
Install the new fuel filter, ensuring proper orientation, and reconnect the lines securely.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes.
Test drive the vehicle to assess performance improvements.
