dtc 0131 & 0151 fix ? did a search but didn't help. is there fix in edit for this ? it is due to headers/supercharger. was happy to see only a few codes, first time playing with efi live. am i correct in saying that when this dtc sets the mil it forces the pcm into open loop fuel mode ? basicly speed density mode. if there is not a fix in edit any other fixes ? thanks for any help, e

Seems like you are having problems with your O2 sensors. If the first O2's are not responding then your vehicle could be going into gimp mode.

it's not running that bad, but, it keeps tripping the ses. both front sensors are tripping so i'm guessing they are not getting/staying hot enough. seems to trigger under load, higher rpms, close to full s.c boost. normal constrained driving does not usually trigger. like to resolve the problem, rather than disableing ses. this has to be pretty common.
