Question 500sl hesitation on acceleration

I have a 1990 500sl,and recently had new injectors installed as well as a new EHA valve.The car starts more or less ok when cold but very difficult when warm.If I press the accelerator pedal once when hot she will start better.This leads me to believe that it may be the fuel accumulator, but when accelarating from a stop position ,the car starts ,hesitates and then goes,this does not happen when the car has been running for a while.
I also have new spark plugs and the car was also serviced.
Any ideas
