So every once and a while my 5.0 swap starts popping and it has a lot of hesitation. It does when it rains or a high humidity day. It doesn't do in all the the time so I could imagine its to lean or a timing issue, otherwise you would think it would do it all the time. I used a 90 mustang ecm and harness. I think it's the BBK mass air sensor I clean it and it won't do it but even if I dont clean it, it will only do it like 3 miles in to my 25 mile trip goes away after a mile or 2 then it's a good all day and after sitting at work for hours and hours it will run fine all the way home. Only when it's rainy/humid or near freezing.
