I have been experiencing the same problem. I dont know if I am getting BAD replacement parts or not since its not fixing the problem....and I am quite sure its the MAF. I think I am going to go get one from the dealer...then I know it is good so I can move on with finding out if it is the MAF or someting else.

With decayed CVV hoses you may a bad CVV now and have some fouled plugs that need cleaning or changing. The CVV may need to be changed as well. Pull some plugs and check for black stains/heavy oil residue.
On the flip side the O2 sensors may be fading on you and need replacing.
That's what I would do, plus look for oil buildup in the intake manifold. You are lean for a reason.

I checked on the intake manafold. All looks good there and I checked/replaced some parts on the intake boot that were iffy parts, so the intake looks good. I believe its the MAF and am looking for a known good replacement.
