Default PO131 code, heavy miss. help

PO131 code, ( o2 sensor circiut, Low Volts, Bank 1 Sensor 1.

Car starts and idles fine, revs fine in neutral no load. Although @ Idel you can here a little popping through the exhaust here and there. I decided too drive the car through the missing and after a few minutes, it actually got better the more I drove it. Once I stop for 5-10 minutes, It will miss heavy again for a few minutes and then start getting better. The car will also back fire a few times here and there when letting off the throttle. My car has shorty headers, STS turbo and gutted cats. TR-6 plugs and newer wires. Then the PO 131 code pops up. Is this driver front O2 sensor? , Thanks

Ususally a exhaust leak will cause a slow to respond code not a low circuit, not sure if this helps but after my tune I threw a 131 AND A 151 so both driver and pass side 02 low cirtcuit, talked to my tuner and he said it is because my idle is set a little lean to help with the surge and he forgot to adjust for it on the sensors,
