Hello I had my Mav ( 2.3 Bauj. 2006 ) converted to LPG car gas and have only problems with it It was installed with me at the advice of my rebuilder`s a STAG 300 system and an electronically controlled flange Lub ! The price of 1900 Euro Inclusive new gas suitable spark plugs was quite OK for me , because Ford for the conversion with the same components requires 2600 Euro . The car in the lower speed range causes problems because it is in the city area and at approx. 2000 revolutions jerks . I have addressed my rebuilder on it and he has also tried several times to get rid of the jerking away but he simply does not get it away . After the last attempt to get the car quiet he told me that I have to live with it because it is an Ami ? It just does not make fun with the car to drive in the city with gas – if I switch over to petrol only is the Ruckeln away ! Who has also made such experiences or the same problem , should I drive to a Ford workshop ? I am doing well and has to give it to me again to sell a car ? Who can write it right back to me ?
