does this look like bad o2's?
 

can some one tell me if this looks like i have bad o2's?

anyone?

I dont have hp tuners I have EFI live, but if your car is running like crap and getting bad milage thats a good indicator. All you need to do is watch the O2 voltage and it nees to bounce from at least 100-900 and back again real fast, if its slow or sticking on one number then its bad.

They look ok on the log.

i dont know what you were looking at, but the switching is vitrually non existent...OP, do you have LT Fuel Trim turned off ?

no i dont have lt fuel trim turned off, they are the bosch rear vette o2's with about 25,000 on them...... So they do look bad then?

somethings screwy...O2's are very "lazy"...LTFT at the end was -5.5 on B1 and +11 on B2 (maybe an exhaust leak).....are your headers painted ?

no not painted, and i dont think there is an exhaust leak, atleast it doesnt look like there is an exhaust leak, had the car on a lift not very long ago and didnt see anything

Haha yeah your right I was looking at my log. I had two scanners opened. Oops but mine look good.

:rotflmao:

ok so if i dont have an exhaust leak, go head and change them then? i know people say those bosch vette o2's are hit or miss with long tubes on an f-body. should i go with densos? seems like those get better feedback?
