Scanmasters # looking crazy

[TURBOPOWERED68]

History
1- last time i drove the car was 11-5-2012
2-The car had a 1/4 tank of 70/30 93/E85

Today
3- Put 4 gallons of 93 and ran it down low.
4-Drove about about another 25 miles
5-Topped it of with 93
6- Drove another 10 miles, pulled over and noticed the numbers.

what the heck is it now????
BTW in the morning the numbers were ok
Throughout the day the numbers were ok
The numbers went crazy,
After another few miles the #s went back to normal.

Compare with the narrowband readings

Agreed... 02 readings? What were the integrator and block learn numbers?

This was at idle.
like a good dummy i didn't look at any other numbers i just pulled over took the video got bent out of shape and pussy footed the car home, got home looked at the numbers again and every thing was back to normal.

Since i don't have any more info and can't get any, what is/are the main suspect(s)?
1-A south going WB sensor?
2-The WB sensor controller is the type that requires re-calibration, So recalibrate the controller? if this was the case it would have continued to read lean and NOT go back to normal right?
3-Scrap the car and never have to worry about this stuff again?


Scanmater check list, if any weird crap goes on again CHECK ALL the numbers. (dumb rookie)

Make sure the right wideband is selected in pl configuration. Maye a different one was toggled by mistake.

That was set about a year or longer ago, and everything was working fine just before and just after. ???????????
The ECM does have a PL bug in it and its getting replaced soon i guess this could also be part of the problem??

your post indicates you believe the scanmaster readings are wrong and the car and the wideband sensor are fine. if you think the wide band sensor is reading wrong switch back to display the narrowband and see what it looks like
af indicates lean , you have a miss..maybe a vac leak ,bad fuel pressure (sucking air) , egr leak or iac issue , why do i say miss .. if you watch the oil pressure its constantly changing as if the rpm is changing
miss will cause rpm fluctuation and could explain the oil reading but ..if rpm was steady and oil pressure fluctuates like that you have another issue

The rpm does bounce up and down (not Much 1 or 200) the car did that for ever, i gets worst if i put it on closed loop (which i always do just forgot to it yesterday) but the o2 readings never changed much.
As far as which one i think is wrong, i have no clue, my guess is that the scanmaster is showing me what the sensors are showing it OR the PL ECM bug is changing its symptoms (which i doubt)

like i said i could look at the NB now but the last time i checked the numbers were normal.
