Well im pretty sure i need a new sensor.. the car has been acting really weird at idle for the past couple of weeks. i have hptuners so ive been logging it and pretty much, sometimes when im stopped at a light for a bit, the car will start to pulsate and the 02 voltage just flatlines and my AFR goes lean past 20 into --- so i was advised to buy a new front 02 sensor and put back in my rear one (took it off because i am catless) what do you guys think? and heres a SS to give a better idea.. any help is appreciated.

 

rockauto.com for OEM

 

thanks alot for that! one more question, they have them listed as upstream and downstream.. if i need 02 sensor 1 (the one that goes into the manifold) thats upstream correct? i just want to make sure before i buy the wrong one lol.. thanks again.

 

yeah i believe that is correct.

 

yup thats the upstream

 

thanks guys.. i hope the one im buying is at least as good as the OEM one on there.. it is a Bosch and they want 52 for the upstream.

 

Bosch is a great brand typically comes with the UEGO Wideband.

 

Thread revive... Was this the correct one? Lol im leaning out at non highway cruising speeds... At wot amd 65+ im perfect afr

 

i had problems with bosch gave a heating error dtc
so i went ac delco/ntk, i got mine from car quest
added the shipping from rock auto and the hassle
of waiting. ya ill spend afew more dead presidents
at car quest, i can return it if does not work and not
worry about shippin it back.
