***UPDATE*** In looking more closely, I noticed the wire harness to the injectors was chewed... Sure enough, taking apart the fuel rail, the wire leading to #5 coil was chewed through - a chipmunk or something... Replaced the harness, car runs like a champ.. Starting my Q70L yesterday, the SAME exact thing happened, and it makes sense - both cars have identical engines, so whatever critter did this, went to the same spot and chewed the same wires... Anyone know a good chipmunk trap??
