Which condition could result from a spark plug gap that is too close?

A spark plug gap that is too close can indeed lead to a potential misfire. The gap is crucial for creating the spark that ignites the air-fuel mixture in the combustion chamber. When the gap is narrower than optimal, the spark plug may not generate a sufficiently strong spark, or the spark may not bridge the gap effectively. This can result in incomplete combustion, reduced engine efficiency, and ultimately, a failure to ignite the fuel mixture consistently, leading to misfires.

Misfires can have several negative impacts on engine performance, including increased emissions, reduced power, and poor fuel economy. Ensuring that the spark plug gap is set to the manufacturer’s specifications is vital for maintaining engine health and performance. Therefore, a too-close spark plug gap can create significant ignition challenges, making it critical to monitor and adjust as needed.
