yes, it defo can be the cam, but this is consistent - ie always does it.

Make sure the knock sensor wires are not shorting where they go into the plug. Also, make sure it's tight into the inlet manifold.

Do you chaps think that anyway possible this fault could also be caused by my actuater or turbo itself? if its not the knock sensor or cam?

The car has a collins actuater on it, maybe if it wasnt set up correctly would it cause this?
