Make sure the driver side front 02 is plugged in. After that it might need an 02 sensor. I've had 2 cars in the shop with the same code.Both had other shops do the install and come to find out the 02's were stripped(common factory problem) and the shops used a torch to get them out.They fried them.

So,reset. If the codes come back quickly change the 02 or go to a shop to diagnos it properly. A lean code means it's dumping 25% more fuel on that side of the motor.
