i just installed the headers the other day and made the extesion that comes with the pace setter kit and barley to day i get a service engine code i plug in the scanner and it shows bank 1 o2 sensor slow response is it killing my hp

 

its going dead replace them but first id check the wiring but im feeling a bad O2..

 

I've got the same problem. One of mine is only showing 100-200 mv maximum and that bank is dumping a lot more fuel in. Usually when those things are gone, they're gone.

 

I am also having a problem with one bank dumping a lot more fuel. maybe i should buy another O2

 

I had the slow response trouble with the bosch o2's, switched back to the delco's and the trouble went away

 

whats the part number for the ac delco o2 sensors the front 1ns

 

anybody

 

25312184

 

The extensions that they give you with the pacesetter headers aren't great either. Invest in some 12" extensions from Summit (Made by casper electronics for flat O2 sensor wires). They are just plug and play, and they're weather proof connectors as well.
Summit Part No:

I wouldn't deal with crimp connected small gauge wires underneath my car where it is exposed to heat, moisture, and dirt daily.

Also -- a lot of people haven't had much luck with the bosch O2 sensors from any local auto parts store. Historically they don't read quickly enough, the delcos are the way to go.

 

how abput the densos

 

I would just go OEM.

 

I had the same problem when I went to tune my car and had the same problem I found it with the tuning software. I was told that the connection would eventually or had moisture and would ruined the connection so I bought the 12'' extensions from summit and all problems solved. Forgot to mention I had the same header set of headers and extension kit it provided which sucked. I hope I have helped you out a bit.

 

1 more q is it true that the o2 sensors do not affect hp cuz ther not used while WOT ? cus i read that on an other forum

 

Heard that too but as far as evidence and proof, don't have any. But you want to have good O2's cuz it hurts your driveability on the street.
