99 4.0L OHV throwing P1152 code

[cr_the_machinist]

My trucks computer intermittently throws a P1152 code. It states "O2 Sensor Indicates Rich / Low Voltage - Bank #2". I've recently put a new MAF and TPS but not becuase of the code. Has anyone had any experience in the past with this code. It causes my truck to run pretty soggy and surge / shutter at cruising speeds. I haven't noticed any change in fuel economy.
