Alfa 159, Brera & 946 Spider
My Alfa 159 turbo gauge reads 0 when at idle with engine cold, but when engine is warm, the gauge is not reading 0 at idle, it reads a little bit more than 0, not much, just a bit.
Is that normal?
I guess it was reading 0 before removing EGR electronically on the car.
MAP is new also...
