help with code 41 o2 sensor heater....changed to 2 different o2 sensors...and still have code...also when trying to rev motor up will not go past 4grand? wtf....boosted d16a6 with z6 head....with modded non vtec dizzy....wtf is wrong...brand new motor also....new valvespring,valves,headgasket,allgaskets,bearings, pistons(vitara),crank is new,block back from machine ship, garrett t25 .80 trim turbo...wtf need help

 

what type of management if its chipped ecu just disable o2 alltogether.

 

true but will it still read my narrowband afr?

 

not if you disable the entire o2

try just disabling the O2 heater

but my guess is you have something else going on...just an O2 heater code wouldnt rev limit you at 4k
