Anyways, when I accel hard, I have knocking noises from the motor. Only sometimes though. I was experimenting with the gas pedal today, and when it's all the way to the floor, it doesn't knock. But if I do it half way, it knocks. Very weird. It's not the lifters (different knock), and it's not the CV's. I just can't figure out what it is and what to do. I have tried all levels of octane: 87,89,92,87+octane boost.....nothing helped. Although the knocking noise wasn't as bad with the 89 octane gas. Injectors? Something bad in the fuel line?? Anybody have this problem before, or know what it might be, please help
