My 90 GMC with a 5.7 TBI motor while it's in gear at a stop idling if i accel. slow just off an idle it runs really ruff until i accel pass that spot.If i accel. fast it will skip past that ruff idle and accel. normal.Also if i want while in gear i can accel. just a touch and hold that rpm where it runs ruff until i accel. a touch more then it starts to accel. like normal.I have recently installed a new fuel pump,and filter but this seems like a sensor or something.THANKS!
