Tirones in Daewoo Lanos

Hello everyone. I am new in this forum and I have a question about my car.
I have a Daewoo Lanos 1.5 SX and when I go to about 2000 - 2500 rpm and accelerate a little abrupt I pull me until I reach approximately 3000 rpm
when I accelerate very softly does not make the case of the pulls.
I would like to know if anyone knows why and how I can solve the problem.
Thank you.

Hello friend, control the state of spark plugs and their cables, tell us to discover, a hug.

Hello friend: it is very possible that they are the spark plugs and cables as the company says. But also check if the pump pressure is injection, if the springs of the centrifugal advance and may important the empty hose that does not suck. Because abrupt acceleration can produce a lot of aspiration to crush the hose, in addition to the injectors that do not drip. I hope it serves you.

Thank you very much for the solution. I have spent only 70 euros on spark plugs and cables. I have invested half an hour of work and the car is great.
This encourages me to continue taking care of my relic of the year 97.
Thank you very much again and greetings.

Hi Minerillo, I'm very happy that you could solve it, a hug.
