Hello, I have the following problem, I have detected the error code P0303 -no ignition 3 cylinders. The ignition strip has been replaced already because of the same error. 8 months old. I have now also new spark plugs in it. But the problem persists and it also runs on only 3 cylinders. Can this be that the ignition strip is already broken again or can it be something else? Can not all ride such a thing buy. Does someone still have idea what it can be or why the thing time and again k aputt goes. Greetings
