Jumping Idle

[93 331 GT]

I took a look at a post http://forums.stangnet.com/showthread.php?t=597269&highlight=intake+pops and saw Jrichker info. I tested the MAF because the car is idling very bad cold to the point of cutting off and when warm my a/f ratio gauge bounces everywhere which wasn't a problem with the old engine I followed his directions and warmed the car up. While running at idle voltage was at 1.19, I pulled the plug and engine shut off. The resistance check yielded a 3.65K ohms at pin D. Oh by the way there was barely anything at pin C when car was running and resistance check. sounds like a bad MAF, but since this only occurred after the engine swap, I would apprieciate a second opinion. This idle situation has been happening for over a week (Since motor swap) and I have already replaced the O2 sensors
