Hello; I did a great service on the weekend (oil, air and internal filters, spark plugs) on the 2008 1.6 Scenic 2 taken over by the parents-in-law. Now it happens that in the not yet warm operating condition in the 2nd and 3rd gear he takes bad gas and slightly “jumps”. After that it runs again perfectly. At the OBD II it shows me on “misfires on one/several cylinders”. I already Googled that the ignition coils are a weak spot – but there before the large service of the The error memory was empty I just assume that I “built the error”… The suspicion with me goes towards spark plugs (yes also logically – the other has rather little to do with the ignition… ). My previous car was a Mitsubishi Carisma GDI – and since there Iridium spark plugs are mandatory, I thought I would do something good to the Frenchman and buy him Bosch Iridium spark plugs. Can this be your opinion the cause of the error? EZ candles… Or do you have any other ideas? Thank you and greeting aiktr123
