01 Busa code 25 Fault with sluggish miss at low rpm - help!

[Wodgepow]

I just bought this and loved life for a solid month, now it is popping error code 25 which is Ignition coil, wiring/coupler connection, power supply from battery. I have cleaned up the battery and it's connections are good. Does anyone have experience with this issue? I hate taking it to the shop.
