The code was probably for a EVAP purge solenoid valve... These are on the drivers side of the engine right above the valve cover and next to the intake. It allows your engine to consume gas vapor from the fuel tank so the hydro carbons dont enter the atomsphere. Make sure its hooked up in the manifold and that there are no vacuum leaks. This sounds like a vacuum leak as any air consumed by the engine that wasnt metered by the MAF is going to cause you to lean out. I would check for a vacuum leak first. They suck to diagnose but usually easy to repair. Good luck
Just follow the fuel lines up to the mani to find it; has a sensor with red palstic on it beside the rails. The hose that exits it goes back into the intake. Make sure it is pluged in and all the evap fittings are too. If it's fine then prob a vac leak like Johawk said.
The first place I would check for a vac leak would be the rubber grommet that houses the pcv valve. It's in the hose that goes into the intake on the pass. side. Those things are POS's. I have replaced 3 when the car was stock.
