Another Little issue

[jmocelts22]

I posted the Rough idle post which does seem to be getting better as i have used the truck, but this past weekend i was down in Boston watching Manny get his *** kicked by the Sox and while driving through the city the truck started to shake while under power like it was missing and had very little power. I had it on level 2 tow which i usually leave it on. It only lasted for about a minute and it ran fine. Later on I was getting on the on ramp accelerating and it started missing again for a few seconds and then it went away and ran fine all the way back to Maine. I don't know if it was a spark issue, a gas issue, an edge issue or what but i was wondering if anyone has had this issue. It alsmost felt like a coil pack issue (I went trhough 4 on my old 2000 5.4) It seems like the edge has some quirky little characteristics that go along w/ it. My one fear of putting something like that on my truck was whether or not it was going to cause my truck problems.

Oh and my truck is an 08 5.4 w/ 18,000 miles, a gotts mod w/ AEM dryflow filter and a Magnaflow muffler. I have a company vehicle so it does not get used and abused everyday.
