My car stalls out of the blue, almost every day. The curious thing about it is that since I've bought it, the check engine light has been turned on, and when it fails this light turns off, just as if the computer was reset for some minutes. When the vehicle stalls, I open the switch and check whether all the lights are on, the only case in which the car starts again. Many times it happens that I open the switch and all the lights but the check engine one are turned on, and then the engine won't start. The scanner has been connected but no code is released (only the ABS code and the Catalytic converter one). Hope someone can help me, thanks.
