While driving my Honda civic EX 2005 with cng installed, and Air conditioner it runs fine but as the duration increases, it suddenly shows a check engine light and engine is turned off....As I restart after couple of minutes on petrol the light disappears and appears again after some time even on petrol.its ocasional, and always with airconditioner, else it works fine. what could be the issue?
Is it related to AC or any sensor or cng advancer??
