have codes on all 4 of my O2 sensors. Is this because i have no precats and my sensors are still in the stock locations? I didnt relocate them because i plan on eventually getting APR Stg2+ software to get rid of the code/CEL. Thanks!

Default if you're gettin codes on all 4 o2 sensors that would suggest a MAF issue. Are the misfires...

consistant? I would log block 3 and see what your mafis reading during idle.

Default shouldnt you log at wot?

when the maf went on my 00my it read normal at idle, but really low at wot. granted it also said left bank too lean, and fuel correction was at 25% or something.

my car was in limp mode though

Default no idea..I think the misfires would be a separate issue. 2 of you O2 sensors

throw codes because they were not relocated properly, the other 2 throw because the MAF is bad?? no idea just a guess-for all 4 of them to throw codes my guess would be a MAF
