Good evening, to introduce myself briefly since I am new here, I would like to say that I drive a Volvo 850 2.0l (126hp). After almost 300,000 km he starts to suffer a bit and so already many parts (coolers etc.) had to be renewed. Of course, it is all the more difficult to separate from his vehicle, you certainly know this here also as incarnate Volvo fans Currently however, I have the problem that the engine usually only runs on 4 cylinders. At the beginning only i m lower speed range and from 3,000 on the 5th came “to that”, but now he has almost completely said goodbye and he tortures himself on 4. I had made an appointment at A.T.U. now to get to the bottom of the problem, but they want to read out the error memory etc. with which I am already at least 25€, moreover I doubt that (what my guess is the reason) the distribution cap is workable as a source of error, or yet? What would you recommend to me? e already thought about expanding this myself and looking at me, but to the lower of the 3 screws is so damn hard to get there I apologize already for the long text but I am a bit thrown up without a car. With kind greetings S3ni7y
