I would swap the CPS with a black or dark purple one, clear all codes and re-test.
The CPS will have no effect on the Buzz Test, but will effect the Contribution Test. This is not going to cure you misfire issue, instead make things a little more cut and dry. It will eliminate the phantom 3&8 misfire that the gray CPS is know for. But I am going to put my money on that #8 injector being bad. Good Luck
