Mercedes-Benz C240 misfire and ignition issues while in traffic requiring solution on Mercedes-Benz C240

Some Mercedes-Benz C240 owners report experiencing misfire and ignition issues, particularly while in traffic, often attributed to faulty spark plugs or ignition coils, which are the most common causes of engine misfires. Additionally, problems may arise from the engine wiring harness, necessitating a thorough diagnosis that includes analyzing fault codes and possibly replacing the harness for optimal performance. In some cases, owners have found that replacing the tappet cover gasket and spark plugs also resolves misfiring issues. To address these concerns, it is advised that owners inspect spark plugs and ignition coils for wear or damage, and consider swapping components to identify faulty parts. If issues persist, further investigation into the knock sensor may be warranted.
