Check Engine Light On. HELP!
Hey everyone, I just put on a set of BBK shorty headers on my truck and within 50 miles the following code came up.
P1151
From the vague description I got from the Autozone guy it has something to do with engine vacuum and a lean/rich condition. My question is, what does this code mean and what is the remedy.(hoping it is easy)
Oh and if there are any OBDII gurus out there please feel free to chime in thanks!

Hmmm. well I hope that it is defenitely not a problem with the headers. If it is just a bad sensor then so be it. I guess I'll go down to the shop and have them retorque the header bolts.
BTW anyone with aftermarket headers experience anything like this? Just interested if i'm the only one or not.

Yup. They weren't even touched during the header install. This is why I am so confused.
Additionally i was told that those 02 eliminators might be needed to make the code dissapear. Why is it bank 2 only and not both?

Speaking of the EGR tube, mine was replaced since the old one rusted onto the old manifold, could a loosely tightened EGR tube be the source of my problems?
BTW: Bank 2 means: driver side of the truck right? Sorry for another dumb question.

A little update here guys. It was a bad sensor! Truck pulls harder and gets better MPG's than prior to the header install.
The porcelin insualtion inside the old sensor cracked from the air chisel blows to the old y-pipe studs during removal of the old manifolds. A new motorcraft sensor from rockauto.com and now the whole deal is fine.
To those who doubted my sensors being disconnected/improperly connected after the install, they weren't. I double checked.
