The problem is relatedd to sensors, I changed the crank shaft position sensor, and it was not the reason and I check the ignition control unit situated under the ignition key, it was faulty and the cause of the issue, but the major problem is unavailability pf this part.
My advise is optra is a good car but never try to buy it, if you have problems its parts are not available
its the common issue with all Chevrolet cars, so is it better to stay away from Chevrolet cars?
