Aid for Fiat Palio Adventure truck

Who can help me with a nod that my truck has when it goes low speed or, in the first or second speed at 10 or 20 km/h,
it feels as if the engine is drowning, even carrying a stable accelerator pressure.
I took her to the agency and someone who attended me there, gave me an illogical explanation as that was due to the computer or something, that what she produced in me was a great disappointment, seeing that they believe that people are so clumsy that we do not reason and in the end it implied that it was better to resign myself to the defect.
I warn that I am driving since the age of 17 and I know those problems, but since it is a new car and I do not know its tricks is that I am requesting this help to the one who finds the same problem and found the solution.
Thank you very much forist friends.

It seems to me that we have the same problem, I have the same truck and the same problem, it seems to me that they come badly, it must be like this

What engine has that Fiat Palio and how many threads it has because it can be as simple as cables and spark plugs and how many motor turns does that defect do.

It has 62000 and it is 2006, the problem is done less than 1000 laps, but it did it from Fabrica, in the concessionaire they told me that it was the engine.

From what you are telling me it can be the engine phase sensor that reflects that the car is behind and varies the advance, the EGR valve or the engine of absolute pressure sensor, check it and let me know and tell me if you can the engine code like this I can look for the electronics or if I have any boletin of that defect.-
