Should a Lean Fuel Condition Be Repaired?

Fuel mixture running lean certainly requires repair. Extended information is as follows: Consequences of lean fuel condition: A lean fuel system requires immediate inspection at the nearest service point. Continued driving may result in acceleration weakness, increased fuel consumption, and in severe cases, engine stalling. A lean fuel system occurs when the engine's oxygen sensor detects incomplete gasoline combustion with excessive air-to-fuel ratio (more air, less fuel). Causes of lean fuel conditions include insufficient fuel pressure, faulty oxygen sensor, malfunctioning mass airflow sensor, intake system leaks, or clogged fuel injectors. Automotive fuel system: The system manages fuel filling and transportation to ensure proper delivery to the engine for operation. It also collects fuel vapors and filters them before atmospheric release. During engine operation, when the ECU detects activation conditions for the canister purge valve, the valve opens, allowing fuel vapors to enter the engine through intake manifold vacuum for combustion participation.
I've been driving for over a decade and encountered a lean fuel mixture issue before. At that time, the car always lacked power during acceleration and idled roughly. It turned out the fuel injectors were clogged. This definitely needs repair, otherwise fuel consumption will keep increasing, and the catalytic converter might get ruined. A lean fuel mixture can also easily cause engine overheating, and prolonged conditions may even warp the piston rings. The repair isn't actually troublesome - first clean the throttle body and fuel system, then check the oxygen sensor and MAF sensor. It can be fixed for around a hundred bucks, which is much more cost-effective than a major engine overhaul.
