WTF can this effect my car so much... my car is stock so obiously cant be a mod porblem...

I would tell you what's wrong with your car but if I did you'd be driving 150mph on public roads.

[third_shift|studios]

what mods have you done to your car? If your o2's are out, and you have stock manifolds, you may aswell buy some headers and new o2's...ya know, since you'll be in there n' all =)

[ls1speedster]

haha..i dont have 1500 layin around

but hey i would like it..

i have heard alot on people replacing this but it doesnt help...all sensors both banks show low voltage..
and like i said i dont run it out alot but it will onlt do 135 and it just wont rise rpm passed 5500...

my t/b is ported

pacesetters seems like the cheap way out..i know thanks for the info..but when i go to do it i want stainless or ceramic..i know them are but i have herd better things with diffrent brands...

people have replaced oxygen sensors before and they have still throwed codes..with low voltage
to replace 4 at 75 dollars each...ouch

wow that might be the prob. thats really hard on a vehicle man. really hard

[Firebirdjones]

Knowing the codes it is throwing would help us help you. Are you saying all 4 sensors are showing low voltage? Have you scanned the car to see what is going on? A code will tell you which sensor, which bank etc....and help you narrow it down,,,so you don't have to spend funds unnecessarily.

On the other hand,,,the front pair of 02 sensors are considered regular maintainance type items anyway,,,they don't last forever and need replacing from time to time. They could be getting lazy.

[ls1speedster]

yea its throwing... both front and both after the cats... i went to my auto zone they plug it in for free and tell you wat it is.... they all say low voltage..

[Getzen_Guy]

X2 Hutch.... especially in the summertime... damn 150 regularly on public roads?!?! lol

[Firebirdjones]

Low voltage on all 4? Well you have me stumped. That would lead me to think a wiring problem of some sort. I would have to break out the GM manual and start going through diagnostic procedures.
