I've had a missfire problem from the time I bought this car. It runs great, idles smooth and is not at all lacking in power. The problem is the cel flashes when I hit around 4000 rpm. I'm starting to think that maybe one of the camshaft adjusters has gone bad and that is why I'm getting this random miss fire. Does anyone know if there is a way to test the camshaft adjusters to see if they are working properly. The car is a 2007 q7.
