Rough idle and a bunch of codes

[Justjake843]

So I'm new to the gm world, and I've got this 11 escalade with 140k with the 6.2, and it's got a rough idle. It's really bad when cold to the point of almost stalling but not as bad when warm. I've got a bunch of 02 sensor codes and usually I'd start looking there, but I've got a handful of codes here and not really sure where to start .

Here's the codes I pulled

P0053 -Heated oxygen sensor (HO2S), bank 1, sensor 1 - heater resistance
Status: Confirmed

P0059 - Heated oxygen sensor (HO2S), bank 2, sensor 1 - heater resistance
Status: Confirmed

P0137- Heated oxygen sensor (HO2S) 2, bank 1 - low voltage
Status: Confirmed

P0154 - Heated oxygen sensor (HO2S) 1, bank 2 - no activity detected
Status: Confirmed

P0300 - Random/multiple cylinder(s) - misfire detected
Status: Confirmed

P1400 - DPFE Circuit Low Input Exhaust gas recirculation (EGR) valve actuator - circuit malfunction
Status: Confirmed

P2270 - Heated oxygen sensor (HO2S) 2, bank 1 - signal stuck lean

P0573 - Cruise control/brake switch A - circuit high
Status: GM failure record

Pics of the truck, please.

You've pulled trouble codes. Do you have a quality bi-directional scanner, to dig down to root cause?

Other members of this Forum much more knowledgeable than me in this area will chime in.
