Typically knocking in your engine is actually from gas pre-ignition.

Try running a tank of premium gas if you're running el cheapo gas. You will also want to take your G to get a diagnostic. Your car is computer and Knock Sensors are supposed to prevent the car from knocking. If it is still doing that, then there is a serious problem
