O2 sensor problem
ok well i finally got my downpipe welded back together and reinstalled the O2 sensor. however, after resetting my ecu, as soon as my car started to boost the CEL came back on. i checked it and sure enough, 41. so could it be that because im running an FMU (yeah i know they suck, =death, will blow up my motor, etc.;please i dont want this to turn into a lecture on why i should not be using an FMU, ive had plenty of those already and it will be replaced soon) that its making my A/F ratio way too rich and thats why im throwing a O2 sensor code?

Re: O2 sensor problem (loopedR6)
02 sensors go bad often. you could just have a bad sensor. there cheap, i would replace and see what happens.
if your running a FMU it only adds fuel under boost, so if your throwing the CEL when starting the car i would say you have other problems. remove the FMU (for testing) and see what happens.
if you have access to a wideband, hook it up and see what your A/F is
platinum.

Re: O2 sensor problem (platinum00)
the O2 CEL only came on once i hit boost. when i started the car and before i hit boost i was good and had no codes pop up.
