Alright, enough bullshitting. :a:
Perhaps we can actually address the question...
My bet is that the problem is electrical.
What kit are you running?
If it isn't the ZEX kit, have you checked continuity at the throttle switch?
If it is the ZEX kit, is the control module still reading the correct voltage on the TPS lead?
If the nitrous supply is being shut off intermittently -- either by a loss of the TPS signal or a crapped-out throttle switch -- it's possible to run pig rich for a moment. :thinking:
