I swapped my batteries this morning and fired my truck up as per normal, everything was fine, running normally for about 3-4 seconds, when the motor started to stutter. It turns out that the EDIC arm is engaging and disengaging, constantly. I disconnected the power, reconnect it and the EDIC arm engages and disengages. Further, I notice that when I connect the power and the EDIC does it's thing, I see sparking on the throttle cable where it is mounted to the firewall. That's bizzarre as there is no electronics attached to that. Also, there seems to be an innordinate amount of juice being drawn from the battery, welding action when I connect the post now. Any ideas?
