I was wondering, if a MAF failure could cause a too rich mixture and bad fuel economy? Im fighting some bad fuel economy and have changed the lambda sensor and plugs, just wondering if the MAF could be a factor, the car does start fine, idle fine, runs great.

Doesnt a MAF failure cause the engine to run lean?

Mine runs a little rich, and reasonable fuel economy, unless I floor it then its very rich, and bad fuel economy
