The thing is, it’s very inconsistent it’s happened maybe 3/4 times over the 4 months of ownership and I’ve taken it into dealership. They’ve determined it’s a misfire but they don’t know what cylinder so they told me to drive it until it comes back to see if it gets logged onto system. Also a lot of vapour comes out of the exhaust on startup whilst idling. I get the error when I accelerate and the car shakes and is clearly misfiring. Then after I start it up again, it goes away for a long time,a month or two and everything is back to normal, like nothing happened.... sorry for hijacking the thread.... im just rly frustrated lolll
