Hyundai Accent engine power loss due to fuel supply issue and possible burnt valves with check engine light on on Hyundai Accent

Some Hyundai Accent owners report experiencing engine power loss accompanied by a check engine light, which may indicate several underlying issues. These issues can include a faulty Engine Control Module (ECM) that negatively impacts engine performance. Additionally, owners may face slow acceleration due to factors such as a clogged air filter, dirty mass air flow sensor, clogged fuel filter, malfunctioning fuel pump, faulty oxygen sensor, dirty throttle body, worn spark plugs, or a clogged catalytic converter. A flashing check engine light is often a sign of a serious problem, such as a catastrophic misfire that could damage the catalytic converter and lead to backfiring. The check engine light serves as a warning for malfunctions in the emission control system, suggesting a range of potential problems that require immediate attention. For those suspecting issues like burnt valves or fuel supply problems, it is recommended to seek inspection by a qualified mechanic to diagnose and address the specific concerns for optimal vehicle performance.
