Looking to see if anyone has had this problem with their pickup. While driving at about the rpm where the fuel injection changes ( 2500 or so ) which is about 80 - 85 mph in overdrive or 60 - 65 when overdrive is locked out, mine pickup sort of coughs for a split second. Sometimes it will do it a few times every mile, then it won't happen for days. It started about 4 moths ago and just did it the odd time. I figured I'd wait til it got worse so the dealer could easily find it, but the last few months it hasn't changed, it's just disconserting. Of course it won't act up for the dealer and they have no idea what it could be. It was new in march and it only has 25000 miles on it. ( 40,000 km ) If anyone has hard this problem or knows what it could be, let me know.

I've had something similar, almost like there's no fuel for a second. I usually have the radio up loud enough I can barely notice, but sometimes the truck skips a beat. It's happened maybe 5 times in 22,000 miles. I just figured it was maybe a bit of water in fuel or intake? It always goes right away...

I just got an 05 dmax and it does the same thing. Only under WOT will it do it and was actually on here searching to see if anyone has had this problem. It does have an Edge box if that makes any difference, but neither of my LB7 trucks have ever done it.
