i've been having a surging issue with my truck between 57-64 mph with cruise control on. it was a very slight surge like the throttle just couldn't find the right spot.
also when i was driving at slow speed 15-25 mph on a very curvy road with the engine brake on, this surge was more like a bucking.
i reciently tried the unplug the egr mod, as i haven't been able to find a steal soft plug to try the egr tube mod.
the surging disapeared, and it appears that i picked up about 3 mpg.
i only have a 100 miles with the mod, but after the next fill up i'll start checking mileage on paper.
