Estimated I am new in the forum and since I do not have knowledge in mechanics I request the help of you.
I have as the title says a Chevrolet Spark 1.0 with 21000 km that bought used a couple of weeks ago.
I have taken the car for refinement to my usual mechanic but there are two problems that it has not been able to solve:
1- Despite being as a new engine and walking well in low and high, as well as the compression of it. But in the morning when I started I must keep it accelerated 20 to approx and let it heat a little because otherwise it goes out (theme that with the Daewoo nuance that had mod 2001 never happened to me). If I turn on the air conditioning to the few blocks it also happens that the engine is turned off when stopping in a corner, a situation that after a while of use no longer happens. The mechanic tells me that this should not happen because of how well the engine is, that if it adjusts it would be accelerated and would have greater consumption of benzine. So I do not solve the subject
2- Despite the tuning that Bencina's performance made to the vehicle is low. It is giving me approx 10 km per liter in the city, without using the air conditioning. It would be to be approx at 13 to 14 km. The strange thing is that 2 weeks ago changes of filters, oil, spark plugs were made. The mechanic says that it does not know that it can be since the Catalitic works well, and the car is fine.
He advises me to take him to a Chevrolet to make him a Scaner with the computer.
So I consult you to see if they can help me and give me your opinion.
Thank you very much.
