Hello together, Vlt can give me one of you a tip. I have already read a lot in the forum but am with my Latin at the end. My Nissan indicates the error P0304, I have already changed the spark plugs, the ignition plugs changed, as well as the injection nozzles changed, but the error persists. As all this has done nothing I have held my connected spark plug to the engine block to see if there is a spark, which was there too. I have no mucus in the water tank or on the oil lid, but an extremely high oil as well as fuel consumption, think because it runs only on 3 of 4 cylinders. When looking with my beginner knowledge I noticed a small “fire wound” (See picture) Unfortunately I do not know exactly which cable this is, but my part dealer meant possibly the Lampdasonde, unfortunately this part is not available, but could it be because of it?, underneath is my battery very weak as my car doesn’t start after a minute of light. But I’ll get it again tomorrow. Does anyone else have a tip? Thank you very much, dear Justin
