When I give it gas you hear a knock it is not a knock that keeps knocking, only when I accelerate fast or when I take off slow then I hear it when it is changing to fourth gear.

This sounds like you have a loose spark plug which will make the noise you have described.

Here is a guide that will help you:

Can you take a quick video of the problem and upload it? The function should be ready by tomorrow (new site addition).

Please let us know what you find.
