Hello guys, drive a Renault Laguna Bj 1998 Grandtour 155tkm 2 liter and have a problem: vehicle runs unevenly, has transition faults and sounds like it runs from time to time only on three cylinders in the error code but nothing is displayed. Have already replaced some parts : -Zündkerzen (org. Renault) -Both ignition coils (org. Renault) -Zündkabel (org. Renault) -Ventile (workshop) -Nockenwelle was checked (workshop) -Zahnriehmen (workshop) -Leerlaufregler erhauert und überp rüft (Werkstatt) -Temperature sensor – exhaust values are fine, was 4 weeks ago at the TÜV War at 8 different workshops, but can not help me, there is good advice expensive, because I have no idea of cars and that is only one of my problems. If you have any idea what helps to solve the problem I will be very grateful to you. Greetings Torti
