Rough under boost, slightly rough idle

I'm getting some really rough running under boost, significant lack in power, accompanied with surging. I also have a slightly rough idle (~= 700 rpm), but only when truly idling, in a hot idle (>1000 rpm) it seems smooth. This started on Friday after nearly draining the battery (headlights on) and jumping the car. It was also really rainy here most of the day. I was wondering if I had an old gremlin back, so I pulled the #1 plug wire (driver front) and it didn't affect anything, so apparently that wire has pulled off. Again.

Would this cause the above issues? It could be arcing and causing spark some of the time maybe?
 
Most of the time, bucking and surging under boost is caused by bad plugs or wires. The next most likey problem is fuel delivery.
