A Little Information About Car:
Model: Daewoo Joy (local name in Pakistan), Matiz (name in other markets) 1.0 ltr
In idle position my car runs smoothly and picks the acceleration as expected, but when the car slowed down at signal/speed breaker and clutch is pressed the car starts to stall or completely stalls. I can only avoid the complete stall by applying more gas.
Car does not stall when only brake is applied but When I press the clutch with brake then the car stalls.
The problem pops out when the acceleration cable was tightened a bit as the car stalling in idle. Later the problem solved but after one day, the car started stalling while running. I visited the technician and he suggested to re-program the complete ECU @ $45 + throttle body cleaning which seem ridiculous as in idle it is alright. By reading the manual http://500.5053.com.cn/daewoo/EN/documents/Matiz/start_matiz.html and some forums, I reset the ECU to let engine re-learn the changes but again after few KM the problem came back.
Please note, there is no "Check Engine Light" and all is working normal.
Is re-programing the only solution OR is this problem related to the clutch?
