Where are the injectors of a Toyota Nadia D4 found on the engine?

In a Toyota Nadia D4, the fuel injectors are typically located on the intake manifold, directly above the engine's cylinders. They are positioned in the fuel rail, where they spray fuel into the intake ports to mix with air before entering the combustion chamber. To access the injectors, you may need to remove the engine cover and possibly the intake manifold, depending on the specific engine configuration. Always consult the vehicle's service manual for precise instructions.
