1991' Mazda 121

Mazda 121 - 1.3 petrol 1991, the car is good, compact, there is a lot of space inside, despite its size, I put a new timing belt, the pump has been replaced, everything is working properly, there is a problem with the injector settings does not gain momentum, the mono-injector setting is needed, in everything else there were no problems and no, in the city 6 liters per 100, and outside the city 4-5 liters per 100, the doors all work completely from A to Z, the problem also with the paint on the trunk peeled off part for aesthetics can be corrected, bargaining is appropriate !
