p0133/p0153 02 sensor slow responce I am currently pulling the p0133 and po153 codes. I have recently replaced 02 sensors to ntk rear Corvette ones. I am having a hell of a time fixing this. So far I have checked pigtail connections to sensors, cleaned the pass head bolt with electric cleaner, replaced maf, checked for exhaust leaks, retightened header bolts to make sure they were tight. I have a scanner I am pulling maf .8 (volts or amps?) At idol and 02s are ranging from high .100s to high .800s. Any help asap would be great as this is my dd.
Please don't let me down ls1tech!

how many crosscounts are you getting in say 30 seconds? that means how many times does voltage cross from high to low with .49 being the threshold. at 2500ish rpm you should be getting atleast 10 crosscounts in 30 seconds.
need to know more about the car for sure if you arent.

were both sensors switching at the same rate?
this code typically means that one or the other primary o2 is lazy (not switching as quickly as the other).
if they are switching at close to the same rate with plenty of crosscounts you need to look at the freeze frame data closely to see what conditions the error codes were stored.

no problem, thats what the forums are for (or should be anyways).
honestly with the amount of crosscounts you are describing i dont see why you are pulling those codes, unless they are just lazy during a certain situation.

these codes are common with having long tube headers... you need to disable the codes with a tune... get them set to disabled or "no fault".... as well as the 1133 and 1153 codes...
