Hey I new to this forum as well and not a female wrench wielder but understand enough to be dangerous. I have a slightly similar issue on my edge here in Texas where it isn't cold at least not today. I get a flutter and kind of a stutter like an older engine missing, all typically below 2000 rpms and when accelerating and when "cold" as in a fresh start but also when accelerating to enter freeways and such. It is just enough to make me nervous. Not looking forward to any expensive repair bills and surely will not be doing any myself. Just want to prevent any bigger issues if possible. I read through the posts above and I too wondered about fuel filters and or injection. Or is she may need a major tune up. I just bought my edge in June of 2016, used and with high miles. Any help, info or pointer will help when dealing with repairmen, please and thank you. I've also got the failed seat heater on drivers side, an a/c blower that might have a short or at least a loose connection somewhere.
