Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools and parts required for the repair.

2. Replace Air Filter

Open the hood and locate the air filter housing.
Unclip or unbolt the air filter cover.
Remove the old air filter and clean the housing with a damp cloth.
Install the new air filter, ensuring it fits snugly, and reattach the cover.

3. Fuel System Check

Disconnect the fuel pump relay to prevent fuel pressure during testing.
Connect a fuel pressure gauge to the fuel rail service port.
Turn the ignition to the "On" position (do not start) and check the pressure; it should meet manufacturer specifications.
If pressure is low, consider replacing the fuel pump or fuel filter.

4. Throttle Body Cleaning

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft-bristle brush to clean the throttle plate and surrounding areas.
Reassemble the intake duct securely.

5. Transmission Fluid Change

Raise the vehicle safely using jack stands.
Locate the transmission fluid pan and remove the drain plug to drain old fluid.
Replace the transmission fluid filter if applicable.
Refill with the manufacturer-recommended transmission fluid using a funnel.
