So a while ago I ordered two brand new dualshock 3 sixaxis controllers off of eBay. Now I'm having problems with both of them. When I'm playing NFSMW my car turns slightly right on it's own when I turn toggle stick isn't moving and when I'm planning MK 9 my character walks forwards or backwards on it's own when I'm not touching the d-pad. I have to beat the controller to get it to stop. Any ideas on what's going on with them?
