when you say screening what do you mean?

teknopete

RF screening (like aluminium tape)
Bear in mind the signals travelling between the lambda sensor & ECU are very small and any electrical interference would give faulse values back to the ECU. This would then in turn cause the system to lean out or enrichen the air / fuel mix depending on how the signal is altered by surrounding electrical interference.

Hope this makes it a bit clearer
