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.

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 ?

TransWS6Am

iTrader: (41)

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

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?
