My GN lost power while driving it today and kept stalling on me.It has a real choppy idle and I have black smoke coming out of both tail pipes .Also my power injection light is flashing and my scanmaster turns on then stays off? Any advise on what could be the problem?

Could be a bad oxygen sensor…

My chip came loose in my ECM all is great now.
Yes, I was going to state that the ECM is in limp mode. It was running from the redundant fuel device (RFD). The AFR was rich due to the limp mode fueling not being set correctly for the larger injectors.
Note that the dash SES light is in the wrong location. That is why the power injection light was flashing rapidly, it is really the SES light bulb. A rapidly flashing SES means the ECM is in limp mode.
