You didn't elaborate on what you meant by figure of eight? Or provide any detail about your configuration, not even which variant or firmware version you have. Or which games you allude to.
Nevertheless, there are lots of existing threads on this subject. Not to mention sensor test apps and the built in hardware test menu. Lots of details in existing threads if you take a look. If you have some unique problem, then you need to elaborate and give us a better description so that we can help you better.
