acceleration

hello friends.
Maybe they can help me with a small problem in car a Biuck 93 6 Cil 3.3, by accelerating a little it stays a moment and immediately responds normal but I feel it does not respond as a couple of days behind, who as information will be Vienbenida.

I can do something myself to solve my problem or recommend me to go with a specialized person.


Thank you very much.

Is carburation, or injection? I suppose it will be injection for the year but here in Spain those cars are not very frequent.
Anyway, if you know of mechanics look at the sensor that measures the amount of air it aspires, the gasoline filter, which is the best dirty, the fuel pressure regulator, also looks to see if the engine has any air intake in the admission collector where you can enter air without measuring the sensor that I told you before ...

and if not, then you will have to take it to the workshop
