Two things I would change....Platinum plugs, throw them out and put in some autolites, next, go back to advanced auto and tell them they gave you the wrong sensors or harness for them, your right about only having 2. If you use a harness for four sensors, the signal will be reporting four a/f ratios and two of them aren't in so they're seeing no fuel now(hence the ECU reporting a lean condition), get the one for just the two sensors. I would bet lots of money that is your problem....
