99 Tahoe p0420
I recently had the P0420 and then shortly thereafter the P0430 codes come up. I replaced my O2 sensors- all of them. I haven't had the code come back up since, roughly 400mi. Now, I had never replaced the O2 sensors and the '99 Tahoe has 164Kmi. Just sharing my experience. Greg- gscherer78ta
