I'm having a similar hesitation as well, after my AOS died. I replaced the AOS and MAF so far and its fairly good, but when cruising or accelerating it pulls strong then suddenly coasts for about 1 second then resumes accelerating.
It recurs at somewhat random intervals of 5 seconds or more in the 4000+ rpm range.
No codes thrown yet.
I did notice the gas cap seal appears to be cracking a bit and wonder if that could be a factor?
If its a Oxygen lambda sensor wouldn't you be getting those codes indicating it was at fault?
