Cm 871 low power gray fuel

[Rockinbexpress]

Hello peeps, I have a cm 871 yesterday if you gave it any throttle the stop engine light would come on and the pedal would go dead. I changed all the filters and cleared the codes today it has low power idles rough and the fuel is grayish black. I sent a sample off to be tested. The codes it had were 1242, 2215, 2448, 115, 1117, 197 any help would be appreciated
