what is going on getting a code for parts i replaced after i replaced another part
alright i had some trouble with my truck which is past, now i had trouble codes for o2 sensors, tps, and mas, replaced all of them, now after i replaced the mas i have code 172 the 02 sensors reading lean in bank one, now is that a specific o2 sensor, and if so which one is it, or is there something else going on thats causing this, when i replaced the mas today and flashed the computer i had 159 witch is a mas code, i replaced the battery last week is it alright to just drop a new battery in and hook it up or do i have to do something i'm missing, idk how i would have an o2 sensor problem when i just replaced them yesterday,
