my #1 o2 sensor needs to be replaced and i was wondering if i should just put o2 simulators for both sensors. i heard that the safc2 will not get over ridden by ecu if you do this so i am thinking about doing it? Will it work? and were can i get o2 simulaters from? Just to check ,how much are new o2 sensors?

 

you cant use a simulator for the first bank it monitors everythin

infact

i only know one person who can setup a simulator but i wouldnt recommend it...he used to be a vendor here...

just keep the stock ones in there last time i checked they were 80 each i think

 

I dont think you can use a sim on the front, only the downstream one. But they are about $25

 

so if i use one in the back will it keep the safc working through all throttle?
And will i pass emissions?
