Yes, knocking, or engine knock, can lead to a loss of power in an engine. This phenomenon occurs when fuel-air mixtures ignite prematurely, causing abnormal combustion that disrupts the engine's normal operation. As a result, the engine may not perform efficiently, leading to reduced power output and potential long-term damage if not addressed. Proper tuning and the use of the correct fuel can help prevent knocking and maintain optimal engine performance.
