Default Another 01 with same problem

My '01 has had similar problems for the last year or so. I get codes PO174 and PO171, more often its 0171. Happens every time I drive over 45-50 mph. It has also started to go through a rough idle on a cold start for about 10 seconds before it settles in.

I attempted to change the MAF after doing some research, after changing it out the engine starts, idles fine for 2-3 minutes and then dies. I switched it back to the old one and it starts and holds idle again. Is this indicating a different problem? I didn't disconnect the battery or anything prior to switching out the MAF, should I? Thanks for your help and advice.
