Too late.  On the way home tonight (jan. 2) the cursed CEL came on. My PCV hose repair wasn't the answer I guess. My hose was in very bad shape (cracking), so I think the shop mechanics probably caused the cut when they were taking stuff apart way back when. Oh well, at least that hose is out of my way.
Even though this didn't solve the CEL problem, I must say that my car is starting and idling after start much much better than before. 
I am planning to replace the ENTIRE plastic hose soon.

MAFs can be faulty, and they are sorta expensive, maybe you can get one from a junkyard at a decent price.

Do you know an approximate dollar amount? Can't be any worse than o2 sensors!

When I changed my MAF 2 years ago it cost me $270 CAD from the dealer.
Bill Jenkins has it listed as $180 USD.
Did a junkyard search found them for $40 - $150 USD.

I thought I needed a MAF once upon a time & priced one at the auto parts store for $68. The guy let me buy it, install it on my car & when it didn't solve my problem, he refunded my money. Problem was plugs in my case.
The install can be handled with common hand tools in about 15 minutes & no crawling around (unless you drop something & it lands under your car directly in the middle where you can't reach it - don't even ask).
To diagnose the MAF, could he just unplug it & let the internal fuel mapping program take over?
Must be that jumbly-wumbly thing happening again.

Quick answer - No.
His problem is the P0171 & P0174 codes, IIRC (this thread has become longggg...). If you disconnect the MAF and operate under the computer's built-in tables, there is no input reference measurement of the intake air charge against which the computer can compare exhaust gas readings. This diagnostic step is useful when there is a gross failure of the MAF, but that does not appear to be the case here.
In my opinion, the MAF is less likely to cause this problem than are the aforementioned air leaks. Air leaks in the intake and vacuum system WILL cause this exact problem.
