For some reason when it's below 20F my car just won't start, it cranks and gets fuel, and gets spark. Somebody at Clarksgarage has a similar problem but their car will at least start. Mine cranks normally but doesn't seem to be firing at all.

I did get it to start today (25F) and it ran really, really rough for a minute or two. And since it seems relevant, it normally has a little trouble starting normally - it randomly turns a little slow or kicks back like it's getting spark at the wrong time, but runs fine.

Everything I've read says Reference sensor or the speed sensor, but I'm not sure if they meant cold as "not running cold" or actually really cold.
