I try to as well but with long gearing, stop signs, traffic, and lights, it's not always a possibility. A number of other people have noted a similar hesitation and mentioned the chip curing it. Could it be the air flow meter? Possibly, but I'm not going to worry about it now.

Also, and I don't mean to thread drift too much here, this hesitation around 3000, was it persistent or more of a random thing? I ask because my '89 3.2 does something similar, but not on any frequency I can determine. Just sometimes while driving (and it normally happens when cruising for a while) it will start to act like it's missing or hesitating in the 3000-4000 range, and not everytime I drive it. The only consistency is that it happens around the same RPM range, but other than that, I have not been able to figure out a cause (not that I've really looked to deep into yet, getting other issues squared away first).

Stock.
Yes, this sounds exactly like the issue I was having. It wasn't every time, but occasionally right around 3000 RPMs and it felt like there was a pause with the throttle but with no associated noise indicating something wrong.
