VelocityS4

I'm not concerned with any of the "Catalyst" codes, or any "S2" codes.. i know i have no cats and i know one of the rear o2's isnt even plugged in. I'm more concerned with the B1 S1 o2 sensor "malfunction in circuit". Bank 1 is drivers side correct? If so thats total BULL because I changed that to zoldmans like 5k miles ago.. it cant be bad! unless something like fried it?
Also EGT sensor "short to ground" thats also bullshh if that means i need to replace it becasue i replaced both EGTs about 8k miles ago.. GRRRR.
I'm also obviously really concerned with all the misfire codes. =( It feels pretty smooth under WOT, so maybe those are from cold start? I get some hickups then, but otherwise it feels pretty fine. Is it possible I'm not feeling the misfires?

Thanks in advance guys!

usually coldstart, since i swapped out to the Bosch Platins about 1k miles ago. What plugs u using and were they torwued to spec?

Imolavirus@BuehnEngineering

B1 is pass.

Ah10@WMS

besides primary and secondary 02, you also need driver side EGT sensor

SForked

maybe the coolant temp sensor?

VelocityS4

I'm running the Bosch side fire plugs, 1 range colder. Yeah they were torqued to spec.

VelocityS4

WOT performance because its closed loop, is that true?

VelocityS4

But why would an EGT go bad when I just replaced it ~8k miles ago?

VelocityS4

Wouldnt I get a code for that?

Imolavirus@BuehnEngineering

I had primarys effect performance because they help with fuel trims
