When you have an intermittent connection, the more often you attempt to light the furnace, the more often it will work or not work. Seems pretty obvious now that I type it.
The wires that I said to wiggle are behind the exterior furnace door around the gas valve. I'm pretty sure they're all low voltage so no chance of electrocution. Wiggle the wires until the furnace comes on.
On my rig, I pulled every furnace connector off and used pliers to tighten up the females a bit. Probably just pulling off and reinstalling cleaned the connection enough to get rid of the intermittent but tightening can't hurt.
