You can go around the engine with a propane bottle opened slightly and if the idle speed changes, you have a vacuum leak and it will also be real close to where the propane is. A dirty or defective MAF would give you some noticeable power loss. Any symptoms besides the code? I seriously doubt the MAF you replaced 85K miles ago is already bad unless you're getting water in it or something.
