It sounds like you may have a vacuum leak, either from the intake manifold or vacuum hoses or a broken or cracked plastic vacuum line elbow, maybe around the PCV valve. Also, I would check to see if the fuel filter has been changed, if the fuel filter is dirty, it could be limiting the fuel pressure and causing a lean condition. I'd check the fuel pressure also.
