Rough engine - the latest pita I'm having to deal with on a string of many!! I'm on a roll!! Ok - hot or cold - engine starts and idles well. Conditions - ISV disconnected due to Idle issues O2 Sensor Disconnected to put ECU in default mode. Cold engine: starts easily, idles easily, but upon attempted acceleration it bucks, kicks, snorts, hiccups, coughs - finally smoothing out at speed. Warm engine: starts easily, idles easily, but upon attempted acceleration it bucks, kicks, snorts, hiccups, coughs - finally smoothing out at speed. Only the bucking isn't quite so bad. Occurs mostly on the initial acceleration after idling successful. Suspicion: Throttle body switches out of limits and need adjusting. Anyone have any ideas about this? Thanks, John
