Mercury Milan #5 misfire with loss of injector pulse after 60 seconds on Mercury Milan

Some Mercury Milan owners report experiencing engine misfires, particularly noting a loss of injector pulse after 60 seconds. This issue can stem from several factors, including clogged fuel injectors, which often lead to a rough idle and are a common symptom of misfires. Additionally, the dual-pulse injection strategy used during cold starts may contribute to increased black smoke, soot, and rough idling, potentially resulting in minimal misfires. Owners also report a noticeable loss of engine power, especially in the four-cylinder models. To accurately diagnose the cause of these misfires and loss of injector pulse, a thorough assessment is essential, which may include checking the fuel injectors, spark plugs, ignition coils, and conducting a relative compression test for any mechanical issues.
