Given my situation, I'm not sure if this should land in OEM tech or Modified. Mods let me know if I'm in the wrong.

(Wiring harness has been modified to run a supercharger)
The other day when I started in the morning the CEL started flashing and the engine ran rough. Code is P0203, injector coil open. The interesting thing is that when I hooked up my USB - ODBII, when the engine is running I keep getting disconnected from the ECU.
So I think it's an intermittent short that is worse when there is vibration from the engine running. But is it ground? Power? Something else? It's only the one injector, and doesn't move when moving injectors around.
