Hi everyone,
I bought a new complete engine for my Daewoo matiz 3 (automatic transmission) a month ago. Initially the fuel consumption was okay until I started facing difficulty in starting the car a week after. I took it to an auto electrician based on the recommendation of my mechanic. After several diagnosis, the issue was resolved but my fuel consumption increased more than twice the initial. In addition, the car jerks when at low speeds especially when the gears changing between 2 and 3.
