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,

 

hmmmmmm, that code usually means out of limits..... try cleaning it, check wires and instalation but i really would just double check the work that was done

 

yeah i'm gonna triple check theplug but thats about it, i treat those things like spark plugs when i put them in, is bank 1 like the sensor on the side with cylinder 1, it looks like i'm going to be going on the search for the receipt, its just weird that it did it right after i replaced the mas, which was also the day after i replaced it, if it was a plug issue or somehting like that i would think that it would come up immediately, idk i guess it could of been defective, just find the recipt and tell them i'm getting a trouble code all ready they should replace it, they replace most of their sensors if they are defective before 30 days

 

oh yeah sometimes when i sit a stop light or stop sign it makes a noise, its like bum, bum, bum, idk what the hell it did it before i had any problems with it

 

any more ideas, i'm really curious about the bum noise
