If my 02 sensors are dead the front ones dose that affect my performance and if yes y and how bad

 

How bad dose it kill u performance wise if both ur front 02s are dead

 

How bad hp wise will the 02 sensors front ones kill u if there completly dead

 

It'll miss really bad and suck more gas than a jetliner. if you go WOT it'll clear up a bit until you start cruising again.
You'll know somethings wrong.

 

Thats exactly wat it dose and my tuner check my comp and it cam out that my 02s were dead line but full throttle the truck feels good dose this mean my truck has more power in her cuz ima swap em out this comming week , so should i just stop Racing till i get em ?

 

No.

When WOT or enough throttle to put you in PE your computer no longer uses the O2's for fueling. You wiill not see any more power BUT it will run a hellofa lot better while cruising and part throttle.

 

thats the same thing i thought but other ppl in forums are telling me it kills me and john from texas speed said that wen i full throttle it the comp is confused so it just trows alotta fuel to be safe so dawm who do i bealive ????

 

In a stock O2 setup the computer only reads and adjust fuel for idle, part throttle situations, just as Bill has said above. I suggest that if you have an inkling that those sensors are bad, you go purchase and install new sensors. I see you have posted this topic three times in this forum, you are finally getting some feedback, think it over. Good luck.

 

The sensors are bad for shure my tuner check it out and they are not reading watso ever but the thing is if they are not killing my performance y go and waist 200 bucks for nothing u get me ?

 

because with no O2's your idle, part throtle and cruising mix will be whack, that's why! Pep Boys has Bosche sensors for less than $50 ea.
