What Causes Delayed Ignition in the Cayenne?

[LeLucia]

Reasons for delayed ignition startup: Poor fuel quality: If the car suddenly changes from normal startup to delayed startup, the first thing to consider is whether you have recently switched to gasoline of different octane ratings or from different locations. Carbon buildup or dirty components: Throttle body: Carbon deposits on the throttle body can affect the perception of throttle and air intake, causing the computer to transmit signals late or even incorrectly, leading to failure to start the vehicle; Fuel injector: The fuel injector is prone to accumulating sticky substances, which can block normal fuel injection, resulting in poor gasoline atomization, thus causing delayed ignition and difficulty in starting the car; Spark plug: If the spark plug has significant carbon buildup or leakage at the junction between the metal and ceramic body, it can cause poor ignition; Battery: Dirty battery terminals can also lead to poor conductivity, affecting ignition; of course, insufficient battery power can also cause delayed ignition startup. Inappropriate oil viscosity: For example, in very low temperatures, high oil viscosity can slow down oil circulation, causing mechanical dry friction, making it difficult to start, and this is very harmful to the car. Insufficient fuel pressure: Fuel pump pressure loss, poor fuel injector sealing, etc., can all lead to insufficient gasoline pressure, thus prolonging the ignition time.
