whether they were positive or negative, i can't recall at the time...but after putting in my New MAF, they went to like 8 & 12 giving me a DTC but CEL. (again, one was negative, i just can't remember)
What gives...i have brand new O2 and MAF in there...

Positive and Negative matters a lot. + is a lean correction and minus is a rich correction. Once things get whacked to +/- 10% there is something amiss. Normal adaptations will range +/- 5%. Either + or - can be MAF related. + can also reflect a Vac leak. - is usually a MAF..

What kind of new MAF? Is it the correct one for your car? 180's take 2 different ones, 225's depending on year can use 3 different part numbers....The output characteristics are different for each. The 180 is particularly susceptible to not running right if you put the wrong one in there

they can really whack those numbers

Yup.....Over 80K, replace em!

I think the second number was usually negative and the first positive. I was getting a rich code
p1137. I'm really confused at this point. As I said, it went from 6 & -9, to like 9 & -12 with one drive, then, i checked it again after a 2 mile drive...and it was 6 & -8
so there's a rapid change in this number. I always though this occurred over time...The numbers are under the 10% threshold, but are still abnormal.
Ehh, thanks for all your help, but at this point, as long as I'm not getting a CEL,...I'm through.
Hopefully, I wont be back about this...Now I got to research this 1287 N249 Open Circuit code that came outta nowhere...
thanks again
