Q. What happens if you don’t change all your spark plugs?
Spark plugs will depreciate over time, so various engine issues will arise if they are not replaced. When the spark plugs do not generate the adequate spark, the combustion of the air/fuel mixture becomes incomplete, leading to loss of engine power, and in the worst-case scenario, the engine will not run.
