Re: 98 GMC Suburban - Multiple O2 codes/hard starting
P0137-151-157 all say the 02 sensors are detecting a "too lean" condition.
P0160 indicates a possible heater problem with that 02 sensor.
"to lean" can be caused by low fuel pressure, contaminated fuel, exhaust leaks, vacuum leaks, PCV valve, etc.
