My VY gets some pretty nasty piston slap on cold start up. I've just assumed LS1's are good at it...

Ok all so i'm starting to think i've found the vibration noise! My power steering fluid resevoir has a leak and the fluid levels were REALLY low so i topped it up and i haven't heard the noise since. As for the lack of power, i'm leaning towards either dirty injectors, a dead lead or a dead coil. Does anyone know how to test a coil on an ls1?

Cheers.

Poke your finger in the spark plug lead end. LOL

Maybe just disconnect 1 by 1 you will hear the car running differently when you unplug it if its good.
I know if the leads break down over time, the car may hesitate etc under load
