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
General Electrical Failures
C0561 - System Disabled Information Stored Engine Speed Out of Range; System Disabled Information Stored Acceleration Pedal Position Out of Range; System Disabled Information Stored Transmission Gear Invalid Data
Status: DTC supported by calibration, History DTC
Bus Signal/Message Failures: invalid serial data received [0x71]
