yeah i just took the smarty out and went for a spin, didnt stutter like it did earlier, but then again, its on and off so maybe it just wasnt acting up this time. i just put the smarty back in and im going to go drive it again to see whats up.
i have seen that in 12 valves autos when they get the govern spring to tight. you are either on the gas or off. cursing = bucking/ surging. there is no in between. im sure that you have the wild torque management program. i would try a mild torque management program an see if that helps. i know you dont want to go backwards in power but it might help until you further diagnose the problem.
