Problem in Acceleration of Car?

What is your question?

I am using it since last 3 years and it was running perfect for first two years but now from last year since i change Petrol Filter(Fuel Filter) now it is disturbing a lot. Whenever switching on the ignition after that acceleration is not getting pick and it might do stoppage during drive. I have to spend 30 minutes after starting car and then i can drive it and even during drive some time acceleration get slow. Please suggest me what to do? Is this due to fuel Filter? or any else problem.
