What Causes Ignition Delay?

[PaisleeFitz]

Ignition delay can be caused by the following reasons: Poor fuel quality: If your car suddenly changes from starting normally to experiencing delayed ignition, the first thing to consider is whether you have recently switched to gasoline with a different octane rating or from a different source. Throttle carbon buildup: This can affect the sensitivity of the throttle and air intake, causing delays or even errors in the computer's signal transmission, which may prevent the vehicle from starting. Fuel injector: The fuel injector is prone to accumulating sticky deposits, which can obstruct normal fuel injection, leading to poor gasoline atomization. This results in ignition delay and difficulty starting the car. Spark plug: If the spark plug has significant carbon buildup or leaks at the junction between the metal and ceramic parts, it can cause poor ignition.
