Clean the throttle body using throttle body cleaner and a soft cloth.
Reinstall the air intake duct securely.

3. Fuel System Repair

If the fuel pressure is low, replace the fuel filter as follows:
- Relieve the fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
- Disconnect the fuel lines from the filter using a line wrench.
- Replace the fuel filter with a new one, ensuring proper orientation.
- Reconnect the fuel lines and reinstall the relay.
If necessary, replace the fuel pump:
- Access the fuel pump through the rear seat or trunk area.
- Disconnect the fuel lines and electrical connector.
- Remove the fuel pump assembly and replace it with a new one.

4. Transmission Fluid Check

Locate the transmission dipstick and check fluid level.
If low, add the appropriate transmission fluid as specified in the owner's manual.
If the fluid is dark or burnt, consider performing a transmission fluid change.
