Another Little issue

[jmocelts22]

I just got back from another weekend in Boston and while in traffic in the city the truck started shaking like it was missing. It was constant while i was idling and a little as i was getting up to speed. Once @ cruising speed it runs fine. It just does not seem to run smooth unless you are up to speed or @ WOT.

I called Edge and they said i should call PHP because my symptoms usually are caused by more aggressive mods than i have. (Gotts w/ dry flo filter and a magnaflow muffler only). I tried calling a few times but have not got through. Does anyone have any suggestions?...
