How do you adjust air and fuel mixture of Nissan Terano?

To adjust the air and fuel mixture on a Nissan Terano, you typically need to access the carburetor or the fuel injection system, depending on the model year. For carbureted models, you can adjust the mixture screws located on the carburetor. If it's a fuel-injected model, you might need to use an OBD-II scanner to check the air-fuel ratio and potentially adjust the fuel pressure regulator or replace the air filter. Always refer to the vehicle’s service manual for specific procedures and settings.
