Sounds like a wiring problem or setup problem on the safc2, if it really was running properly with no codes before. Safc shouldn't have any affect if the graph is +/- 0
So far you have a code for afm and knock sensors?
Obviously knock sensors need to be hooked up stupidest thing not to run on any turbo car
Safc knock wire is for monitoring only I believe
