Hello forum, but since a short time and out of the blue I have a rapid power break in warm engine. It feels like a cylinder will fail, which I want to exclude. Short error description: At cold start is the full power and completely normal driving behavior available. This keeps itself without problems, until the engine is warm after 10 to 15 minutes. A short jerking and the engine sounds like a trecker and has no more power. Also the engine switch off and turn on again shows no effect. Only after the engine is properly cooled down is again full power available and no start problems. I exclude spark plugs now – I have just changed them. The ignition coils are it m.M. also not, since I have no ignition triggers but from a certain time permanently the problem described above. Maybe someone knows the error picture or has a tip. I have the feeling a sensor o.ä. is defective. Thanks for every tip! VG Simon Ps: Volvo V40 – Bj.98 – 120tkm – 2.0l Sauger – Automatic
