so what did they do the exhaust manifold,?
most of these cracked on #4 runner long ago (far rear)
you said the O2 stripped out?,so how was that closed. (them moved the O2 right?
if you have this. damage, here, below, the 02 can never work right, even making it dead on fuel trim stuck at OL mode. open loop
that uses lots more fuel and will cause hesitations, and misfiring and red hot CAT and fueling problems/
this photos is mine and all shields off, to see the CRACKS, the cracks suck air and the 02 slams to zero 0 volts DC< and EFI goes rich,,. no leaks here allowed ok?
