Message	Having hesitation at light/moderate throttle. When I monitored the o2's, I noticed the driver bank is running very lean. Even when I'm parked there is a hesitation/misfire along with puffs of smoke ( blue/gray) when I hold revs at 2000 rpm. Sometimes it smokes when the car has been idling for a minute or two. Weird thing is the car runs fine with the o2's unplugged. I'm guessing it's dumping the extra fuel necessary in open-loop?
