Alfa 159 cold start problem when on tilted surface

Hi All,
I have noticed recently that when i park my 2006 1.9 JTS 159 (90k km) on a tilted surface, does not have to be very steep though, just mildly then i have trouble starting it. The engine fires but after just a 2-3 seconds it starts to rattle like there is a problem with some cylinders not working and the engine stalls. After 10 tries and giving it some revs it stabilizes. Also the dash oil temperature light blinks once or twice.
There is enough oil - i've checked - i use 10w-60 because after the folks in AR changed my timing chain the engine started to click and i never got rid of it since. They have replaced the chain, variators (those 2 ) , 2x crank shafts, all hydraulic lifters and the problem still persists. The oil makes it quiet down a bit .. but only a bit. So there are actually two problems here, if anyone has experience with this, any suggestion is most welcome.

PS: I have a diagnostic cable and the multiECUscan software and no problems there.

Alfa 159

Allrighty, so i managed to hook her up to my computer and get the error codes:

P1175 Mixture 2 strenghts (multiplicative)
P0300 Ingnition failures (generic)
P0304 - Cylinder 4 ignition failures
P0303 - Cylinder 3 ignitioin failures

Any Ideas what might be the issue here ? Lambda ? Spark plugs ? (changed a year ago) Or something with air intake or exhaust ?

Not sure how it can be related to the slope, unless the oil, or fuel is low somewhere? Possibly weight of engine resting on some cables and giving bad connections?
