I would really appreciate any good advice from an experienced Fiat mechanic or a good connoiser.
I found 1 problem... the vacuum pipe on the MAP sensor was disconnected. Engine is now more stady and fuel smell int the oil has really decreased. On the other hand, i still have some white smoke and fuel smell coming out from the tailpipe but
I noticed when the engine come to it's hot temperature (close loop) this symptoms almost disapear.
Maybe a bad o2 sensor?
All i hope is that its not the piston rings as i wait for my compression tester.
