O2 sensor problem p0135
iīm in a battle whith my O2 sensors in my Vette
iīm only running the front sensors not the rears....
i was always getting this code p0135 and itīs a heat code for the driver side o2 sensor, but i decided to swappe the sensors drivers side to passengers side and then like i thought i got a code on the passenger side one.p0155
so i installed new one only 1 though, because the both i was running before where only 2000 miles old
and it worked fine for 300-500 miles then it started throwing p0155 thatīs the same code as before only passenger side one.
so i decided to try to use one of the old rear ones i had before (heard they had better heaters) and it worked great for 200 miles then the new one i installed before started to throw p0135

so i was very sad about that but decided to try the other old one i had and it has been working fine for 800 miles but now it started again p0135 just few minutes after i start the engine, but if i clear it out it doesnīt appear again, only when itīs cold
So that leaves me whith this....
1. either there is some failure somewhere in the car?
then what could that be?
2.or my car is fauling all my sensors fast as hell (it has been a bit on the rich side) iīve been tuning it
so then what sensors are good for me? heard that bosch was te best.?
are there any one out there who know what could be my issue...

thanks

thanks for your help

you would need to pull them off and sending them to check it. do this last..
F/R : what is that?
Fuel/Ratio. if your tuning your car how/what program are you using? HPtuners or something like this is what you need to check F/R and better yet get your self a F/R gauge for precise tune.
