The codes are saying that the oxygen sensors are reporting a lean condition (more air than fuel in the mixture). You could have a vacuum leak and probably a large one. Causes for that could be a loose or bad fuel cap, a hose that came off or split, a plastic fitting that broke, a intake manifold gasket that failed (or the manifold itself cracked), the diaphragm in the brake booster ruptured, the brake booster check valve failed, the egr valve is sticking open a little, the egr gasket has failed or the egr pipe has a hole in it. On the fuel side if your fuel filter is clogged or your fuel pump is getting weak that could do it also. Thats all I can think of at the moment that could cause a lean condition
