I've read that o2 sensor isn't always caught in ECU diagnostics, perhaps try replacing it? Should only be a few bucks and one less thing to troubleshoot down the road.
Vac leaks can cause the MAF to tell ECU to dump fuel and can adversely affect your AFRs depending on the severity of the leak, look into those next!
