Rough & Low RPM Idle During Winter - Cross Post, but maybe someone here can help!
I seem to have a rough idle issue with my car so maybe someone here can help.

Guys the V12s can run high fuel temps and sometimes on warm days if you have a "winter mix" of fuel from your local gas station it can actually boil in the rail, form air pockets, and cause hiccups in your fueling system that will show a CEL and misfire codes. It's normal and happens to me every November/December. It will work itself out and actually the CEL codes wind up going away by themselves.
