Hello, I mounted your kit on my Audi coupe 2.3 Ng , everything is ok , she has good start but when I drive the car has hole on acceleration and make big vibration. The invent commander says that my lambda is faulty, I replaced it with a new one but same problem. The correction is also a lot and the lambda voltage is not stable . Have you an idea how to check if it's the lambda is well powered? Or anything else ? Thanks for your help
