Not that this is the reason for your problem, but I had similar symptoms with my VX a while back. I only noticed it on the freeway or on a stretch of highway, sometimes while accelerating slowly from a stop and traveling a prolonged time at a certain speed.

The strangest thing... I found that it was my shoes that caused the problem. For whatever reason, whether the shoe was too long for my foot or what, IT caused my trucks hesitation. When I wore a different pair of shoes, I never had the hesitation. I have since gotten rid of those shoes and have been hesitation-free ever since.

Go figure..;eekr; ;Dr;
