I have been searching but everything I find seems to just be responces about changing the fuel filter.

When I am on the freeway doing about 70mph in tow haul mode with a ~6-7K trailer and once w/o a trailer the engine will loose power for a few seconds and then come back. It happens typically at constant throttle, and neither the boost, trans slip, or egt's are higher than the defuel limits. It's an 01 D/A with edge/Attitude. I am typically on level 2 but have had it happen on level 0,1, and 2.

I have changed my fuel filter with the same result. The last trip I was on a slight grade and it happend, and this time set of the "service engine soon" light. I don't have a code reader or know anyone who does, and autozone won't scan codes in California anymore. I am wondering if there is a solution before I buy EFIlive to scan it.

i would trry to disconnect the edge first and go to see if you can get it to do it when the truck is stock..even with the edge still at 0(stock) it is still going through the edge. I think its probabley the edge getting all screwed up. where in cali are you located???

I'm located in San Jose, Ca

nor cal i have a buddy that lived in san jose and just moved to roseville. have you tried to just run your truck with the edge disconnected yet??? I would just try process of elimantion. my money its the edge

I'll try that this weekend and report back.

Just get rid of that thing! All you need to do!
