Assalamo a alaykum
I owned a Chevrolet Exclusive 2004 from last year, the car is no doubt very comfortable, smooth drive nice road grip and good fuel consumption. But from the first month I am facing the same problem which is giving me a headache & has not resolved till now.
The Problem is when the car gets heat up after driving for 30 mins or about 15-20 KMs the engine shut off automatically when I slow down the car on signals,stops, turns etc and then it does not start until the engine cool down again. And the likeliness of this happening depends on the heatness of engine when I drive with AC car heat up more and problem starts early. While I drive it on petrol it can run longer upto 30-40Km before problem start.
During this time I have change the radiator with new, water body, Starting Coil, get fuel injectors service, fuel pump change , CNG Emulador with wiring has changed with new one but still same problem.
Recently I once again changed the starting coil and check for 3-4 days but still the same problem.
Yesterday on a recommendation of a guy I tried to reset ECU by plugging out the negative terminal of battery for 30 mins and then plugged it in again then I start the engine on idle for 10 mins then turn on AC for 5 mins turn it off then again on for 5 mins until the car reaches a constant rpm.
After this ECU resetting (I am not sure weather it has reset or not) I went away for a trial to check the car's condition and now the result is worst now.
Please note while the car is running it is perfect no missing or any other issue the problem starts only after some KMs of driving.
I have been to several mechanics but no one has comeup with a solution despite fail attempts.
What I should do now.
Please need real help here.
