O2 not ready, not drive cycle Having trouble getting the car through emisions. O2 and heated O2 sensors are showing not ready on my 05 GTO. Car has had about 2k highway and street miles on it since it was tuned so it should not be a drive cycle issue. I'm not getting any CEL on he dash or stored in the memory.
Car is an LS3 engine swap w/ an aps tt kit, cats are gone. Could the sensors be bad without throwing a code?
