What action should you take if your engine is running rough?

When an engine is running rough, checking the ignition components is a critical and logical first step. The ignition system includes parts such as spark plugs, ignition coils, and wires that are essential for proper engine function. If any of these components are faulty or malfunctioning, they can lead to improper fuel combustion, causing the engine to run unevenly or rough.

Identifying issues in the ignition system can help diagnose whether the rough running is due to electrical issues, a misfire, or even flooding in the engine. By checking these components, you may find a simple fix, such as replacing a worn spark plug or a damaged ignition wire, which can restore the engine's performance and prevent further damage.

Taking immediate action like this is generally more productive than ignoring the problem or accelerating aggressively, which might worsen the situation and potentially lead to more severe engine damage. Stopping the vehicle can also be a valid choice depending on the severity of the issue, but first assessing the ignition components is a practical and proactive approach to diagnosing and resolving the problem.
