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.

Is the tune you were running canned or custom?

Did this just start out of the blue?

Could be a moisture issue, if you've been driving in a lot of rain and water has gotten into the plug boots.

It is the canned level 2. It is still acting up a little. I usually notice it while driving slow but on the gas. It kind of stutters a little. @ WOT i don't usually notice it. The Edge has been on the truck for about a month and i just started to notice it.

Since its an edge product try to call them and see if they have any thoughts.
If you don't get anywhere with them then try to call PHP.

I have the same issue on occasion running the gryphon with an 89 custom tune on my 06 5.4. I had other issues in the past with the tune and Bill was able to fix most of them but this issue is still ongoing. I have not removed the tune lately to see if it does it stock but I probably should at some point.

thanks

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?...
