What's the difference between the upstream o2s and the downstream o2s? I got my hands on a brand new pair of ac delco's (FO FREE!!!!) but checking the part number they are the downstream sensors. I'm thinking there won't be alot of difference, and my front o2s are COMPLETELY shot.

 

yes they r different no you can not use them

 

by the way you better get your ship together cause i'm going to have the video mounted in the bed so we can see just how far i beat you

 

Thank you for ruining my chances of getting the truck fixed now. I hope that camera has a remote swivel on it so you can tape what's in front of you.

 

What's different about them, randy?

 

Ive been running the rear O2s in mine for a while and they seem to work fine.


I just pulled the pins out of the plugs and swapped them to the other plug.

 

hey try them i know on my truck they did not work try it cause i want to smoke u'r ***

 

Whenever youre ready buddy (anytime from now till about 7pm tonight) I pick the track though.


Seriously Ive been running my rear O2s since I gutted my Y pipe, then I picked up a set of Fbody rears and thats what Im using now. Been using them since March (Or after March when my truck came off the jack stands with the new "black beauty FLT")

 

try and cross fingers

 

John said he has been running rears on his truck with no problems. Of course, he did fry a 6.0L.
