Experiencing a check engine light in your Mercedes-Benz C200K accompanied by a misfire can be frustrating. A misfire, often indicated by a rough idle or loss of power, is a common issue that can stem from several sources. However, for C200K models, failing coil packs and worn spark plugs are frequently the culprits. This article will guide you through understanding, diagnosing, and addressing misfires related to these components in your Mercedes-Benz C200K.
A misfire occurs when one or more of your engine’s cylinders fails to ignite the air-fuel mixture properly. Your Mercedes-Benz C200K’s Engine Control Unit (ECU) is designed to detect these misfires. When a misfire is detected, the ECU may cut fuel supply to the affected cylinder to prevent potential damage, which results in noticeable power loss. Initially, you might notice misfires primarily under heavy acceleration (Wide Open Throttle – WOT), but as the issue progresses, they can become more frequent and apparent even during normal driving conditions.
