Have you checked your cats to see if the welds are leaking? That was my issue after replacing the O2's with Bosch

they have heat shields. You may try the old vacuum to the tailpipe truck. For me I could hear the leak under engine load. I removed the y pipe and demmeled the heat shielding off and sure enough the weld was toast
