Hello forum! For some time now my car (Chrysler Stratus LE 2.0, BJ 97) had problems with the acceleration – at times there was a little jerk, as if the engine would not get fuel for a short time. Now the problem became worse and worse and occurred especially at low speeds and when starting up. At first I thought of a broken petrol pump, because I had the same symptoms with another car before. But since also false ignitions joined me, I have a Blic k thrown at my spark plugs and: 1-3 is fine, number 4 swims in the oil. And I mean what I say: it swims. My question: 1. What is this about? Oil scraper? 2. How do I do it all over again? Hope someone can help me.
