Explain the steps involved in disconnecting a multiport fuel injection
While discussing electronic fuel injection principles: Technician A says that the PCM always adjusts the air-fuel ratio in response to the O2S signals. Technician B says that cold air is dense, which is why the PCM enriches the mixture when the engine is cold. Who is correct?
