If your TPS or O2 sensor is out of whack, this will cause the conditions you describe. My personal guess is leaning towards the TPS as it is dominant towards higher RPMs. Youll find it towards the front, left side of the carb. If theres not a connector there, ignore everything i just said:P

drg84, i need to know what year they put TPS switches on q-jets?
