First check your digital side car and make sure all 3 power lights are on. Unplug from the cRio to make sure.

If they are not, your spark could have caused an issue on the digital side car.

If those are on the next item to look at would be the PWM routing. Do they come anywhere near the power wires going to the motor? If so try moving them far away. We had an issue last year where the power wires for the motor were right next to a servo line. The induces voltage from the variable speed on the motor lines cause jitter in the servo. When separated that problem went away.
