Rough running only when abs light is on?

[neverendingproject]

Me and my father just rebuilt the injectors and replaced the sleeves in the heads, and it ran fine for a bit, but now it only runs rough when the abs light comes on, or vice versa. All I know is that it runs like a champ if the light is of, and black smoke 6mpg and no power happens when the light comes on.

Oh, and I did search, but no luck. Unfortunatley the sleeves didnt help the fuel leaking into the coolant, but just getting it running is the big priority right now.

Thanks in advance for any help.
