P0171 and P0174? If so, check the IMT O-rings, the brake booster check valve and the PCV hose. Like JagV8 said, search on here for either the codes or the specific pieces I mentioned and you will have a good chance of fixing your problem. If you have different codes than what I mentioned, then post here or do a search for them and you will find a number of good answers. Vacuum leaks are probably the most common cause for lean codes.
