Got a p133 code O2 sensor,insufficient switching. Hooked up a scan tool to look at the o2 sensors and saw that the sensors are switching back and forth . So I replaced all of the exhaust gaskets along with the gasket in between the head and header and the heated o2.I also hooked up a vacuum gauge to find no engine leaks and no other leaks found this code has been on for a wile now and I tried to clear the code after I worked on it and it still is coming on what do I do next
