Should a Lean Fuel Mixture Be Repaired?

[SanTucker]

Of course, a lean fuel mixture should be repaired. Additional information is as follows: 1. Consequences of a lean fuel mixture: If the fuel system is running lean, it is necessary to immediately go to the nearest repair shop for inspection. Continuing to drive may result in reduced acceleration, increased fuel consumption, and in more severe cases, engine stalling. A lean fuel mixture occurs when the engine's oxygen sensor detects incomplete combustion of gasoline, characterized by too much air and too little fuel. Causes of a lean fuel mixture include insufficient fuel pressure, faulty oxygen sensors, malfunctioning air flow meters, intake system leaks, clogged fuel injectors, etc. 2. Automotive fuel system: The fuel system is responsible for fuel filling and transportation, ensuring that fuel smoothly reaches the engine to power its operation. It also collects fuel vapors, filters them, and releases them into the atmosphere. When the engine is running, the ECU detects the conditions for opening the charcoal canister purge valve. Once opened, fuel vapors are drawn into the engine under the vacuum of the intake manifold to participate in combustion.
