Does anyone know what could be the cause of this. It happens frequent now. The coils and plugs are new which I had to change either way cause of the age of the car but it’s been doing it even before I replaced them. Did a carbon clean up thinking maybe that could fix it but it still does it. It does it when the car is cold and warm. That lil short crank no start then I would have to try again and it would start but sometimes rough tho. I attached a video hopefully you guys can see it

 

Coilpacks can malfunction with age but they don’t degrade or have a certain life expectancy. There is no reason to replace them unless you have been able specifically diagnose one of them is malfunctioning. There is no reason to replace them all at one time. It’s hard to tell what the problem is from the video, but I didn’t see a check engine light on, which you should always get when there is a problem with the engine or how it’s running. So if there is a problem with the, it’s probably not something specific to the engine. It could be something like a bad motor Mount or something? Can you explain what the problem is a little better?
