From cold, in 35 degree temps, it took 4.5 mins idling to go into closed loop this morning.
I don't know if any of the o2 sensors have been replaced. Car has 125k on it.
I'll look for blown fuses next, I can try to check voltage on heater wires too.
After driving 15 mins and then idling again post cat sensors read .7v bank 1 and .08v bank 2. Seems low on bank 2
