Sputters and shakes

My idle... smooth as silk.

from 1k to 2.5k, shaky and the car sputters...
from 2.5k to redline, smooth as silk, clean and sounding great. The car is a bit rocky off the line but it gets past 2.5k in a hurry and we're fine. Also at 2.5k is where my car is at 55 mph in 5 gear and there is a bit of stuttering.

What's wrong with this picture.

Also some back fires on decelleration when engine is cold and into the 1k to 2.5k range. When it's warm there is no back firing.

Have a 1974 2.0 with original injections system.

I'd check the injector seals. They let air in on decel and can cause backfiring and will cause missing/shuddering on accel. The plastic tips also have to be there or the inner seal will not work correctly. Good luck.
