you can log them, but if they are bad, how will you know what good ones look like (past logs maybe)?
i don't run NBO2's so I can't tell you what to look for, but I know they'll kick your ass if they're bad

Damn, how much are they anyhow, not too expenssive I assume?Originally Posted by TAQuickness

not bad, Bosche 13111's are about 75 each in my neck of the woods.
I just dont want to fork out 150 bux and not fix the problem

compare your logs to old logs and see how it looks.
Thats what sucks, I never logged the O2 sensors

No DTCs?

Your WB says you're running rich;
Log the following:
LTFT1 or LONGFT1
LTFT2 or LONGFT2
HO2S11
HO2S21
If your NBO2 sensors appear to be working, the HO2S11/HO2S21 will:
at WOT: peg at something like 800+mV;
at PT: switch up/down (i.e. cross 450mV in each direction) [almost] repeatedly;
If they are doing this, then what do the LTFT's read...?
Does this correlate with the WB sensor...?
Are the LTFT's deviating from zero by more than 5% (say)...?
Rich or lean...?
Are you running a MAF...?
If so, log MAF and MAFFREQ and see that they correlate to TPS and RPM.
Well this problem is still on-going... I dont know what else to do.
I've checked all of the following:
Injectors (not leaking)
Plugs (nice and brown)
Plug wires MSD (look to be working fine)
Vacum hoses (all fine)
Checked for broken valve springs (checked all fine)
Checked the header primary temperatures with an infrared thermometer and there was some differences off about 100F on a couple of cylinders. Need to check again tomorow to see if the readings are the same.
I appreciate all of you guy's help, but I'm still too new with EFILive to know what to and how to log certain parameters and know how to read the results.

Use the EFILive scan tool to do the Cylinder Balance test.
Then you may also want to do a compression/leakdown test.
