since my replies/post i've had the truck in with 2 dealerships, and just by chance, for whatever reason, the weather seemed to be quite warmer or whatever, but in any case, the truck wasn't having the issue, at least distinctively while on the way to my appointment or while the tech was driving/looking at it. They were very willing to work with me, but just couldn't reproduce the problem, and neither could I, what timing!

anyway next time the problem seems consistent, I'm going to try to run it up and have them look at it, and keep you all updated in case anyone else is keeping an eye on this.
For those who are having this problem, or have had it fixed, do you have any other details about when it was or wasn't occurring, and if it was or wasn't consistent, because it definitely seems that sometimes, it's not even an issue at all, but other random days, it definitely feels like something is wrong.
