I bought c4 sx 1.4 2008 LPG converted and after couple KMs it started engine stopping when I stop automatically when running on LPG, after scanning fault codes it showed p0170 p0172, the petrol system becoming unstable and hard to start at the morning, after clearing the faults it's become better but it will back again in few KMs after using LPG, at the petrol usage after unplugging LPG system the car is running very well,
even I have changed injectors, spark plugs, an expert has checked the ECU and I even changed the LPG system from ULTRAGAS to ATIKER one
, my fixer said the the previous owner seems changed the valve,
I'm using OBD2 for clearing faults almost daily to run the car.
No one has an answer in my town for this problem and i hope that someone can help me in such a case.
