Remove the air filter cover by unscrewing the clips or screws.
Take out the old air filter and inspect it for dirt or damage.
Install a new, clean air filter, ensuring it is seated properly.
Reattach the air filter cover.

3. Examine Fuel Delivery System

Tools Required: Fuel pressure gauge, wrench set.
Locate the fuel rail and connect the fuel pressure gauge to the Schrader valve.
Turn the ignition to the "ON" position (do not start the engine) to check fuel pressure readings.
If pressure is below specifications, inspect or replace the fuel pump and filter.

4. Clean or Replace Throttle Body

Tools Required: Throttle body cleaner, soft cloth, socket set.
Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reassemble the intake duct securely.

5. Check Ignition System

Tools Required: Spark plug socket, torque wrench.
Remove spark plugs using a spark plug socket.
Inspect the spark plugs for wear or carbon deposits; replace if necessary.
Reinstall spark plugs, torquing to manufacturer specifications.

6. Inspect Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel.
Check the transmission fluid level using the dipstick.
If low, add the appropriate type of transmission fluid until it reaches the correct level.
If the fluid is dark or burnt, consider a full transmission fluid service.
