Last Driving, all was normal, the Short Term Fuel Trim at both Banks was nearly equal.
I think, i have a Temperature dependent Leak, i bet its at the PCV System.
But, i've fillet the half empty Fuel Tank with E85 (85% Ethanol)
so it may be, that the Injectors are cleaned now.
My Mind... Most time, the Car is running on LPG.
But on the last 300km i leave it on Gasoline and so it may be, that some Injectors, were clogged a little before, and now the Ethanol has cleaned it.
So i have to watch and investigate.
I'm not superstitious.
It brings misfortune
