Had front left axle seal replaced last week, a few miles later the abs/brake light came on. Figured I’d drive and let it cycle a few times. Noticed some intermittent feedback in the brake pedal like abs was engaging. Light would go off after parked and come back on after a few miles. Also noticed a miss in acceleration followed by the abs light coming back on. Fuel pressure fine. Would an abs sensor issue explain the engine miss? Abs module was rebuilt a few years ago, rear speed sensor is new. 

No. The ABS is most likely a speed sensor. The misfire is going be separate. You could unplug the ABS module to see but I doubt it will change the misfire.
