Yes, a car can start with a bad air flow sensor, but it may run poorly. The engine might stall, hesitate, or run rough because the air flow sensor provides critical information for the engine's fuel injection system. Running with a faulty sensor can increase fuel consumption and potentially cause damage over time. It's advisable to replace a defective air flow sensor to ensure optimal vehicle performance and fuel efficiency.
