Hey all, it has been pretty cold around here lately. Roughly 10-32 degrees farenheit. My truck keeps throwing a DTC, po172 and 175. Bank 1 and 2 are too rich. Is it because of the air is so dense and cold that their is too much fuel. It doesnt make sense in my head. It has been guzzling gas the last few weeks, and am getting tired of it throwing codes, and being sluggish as hell. Any help is appreciated.
