My Honda Partner does not accelerate well, he suffers when accelerating

Good morning and I already appreciate your answers, my problem is as follows, I have a Honda Partner of 97, I worked normally until one of these when accelerating it did not obey the accelerator, I stomp There is an engine response accelerates well slowly, it is the automatic box the changes if they are made normally for what I suppose is not the box, with a friend we change the filter of gasoline and normal work, but after a month the same thing happened again, we changed the gasoline filter again but it is still the same, estimated friends of the community you have more experience that you can help me and remain very grateful.

Hi Jhackcp.
In the fuel tank outlet valve there is a sieve that also obstructs, another possible cause is the air filter or the spark plug that already asks for restitution, verifies that the exhaust tube is not covered with coal, a carburetor cleaning does not left over.
Luck.

Greetings, it could also be the covered catalyst. Habria that she reviews it.

Hello, thanks for the tips I still do not check the car, they told me that I could be failing the fuel pump, will it be possible?

Hello everyone, Jhackcp, for the symptom that describes, if also the witness of the faults of the injection (check Engine) is off when the engine works, most likely it is a failure of the fuel feed system, I would start checking what Mr. Servilimit Express, the filter or sieve they carry before the fuel pump, apart if you refers to the filter and I walk the filter. It is likely that this is just (sieve or clogged prefilter), usually due to accumulation of dirt in the fuel tank. If this is fine, check pump. In those cars if this is and you accelerate the engine very gently, it should fail less, that if you accelerate sharply due to lack of a fuel flow due to the covered filters. Safe and luck.
