throttle hesitation in 91 audi quattro 100
 

I have a 91 audi quattro with a 2.8 five cylinder and there is a very slow throttle responce. I have done a tune up and it did not seem to ahve any affect in that area. Does anyone have any suggestions. i am thinkin it might be stariving for fuel and it also sometimes acts like it is cuts off and then takes off again. any help would be appreciated.
