So it was very cold this morning. It was -19F (-38 with windchill). My car barely started. It was running very rough and it stalled a few times.

I'm thinking it's having a hard time to start because of the colder sparkplugs I'm running in the car. Right now I have BKR7E. Should I put stock specs sark plugs for the winter?

shiit. . . thats cold.
Make sure your car is rich enough, I imagine it would lean out alot with those kind of temps. .
Sorry I can't help with the problem. Is your battery up to date?

Fuel atomization is probably really poor. Maybe you could try using a block heater and running the intake manifold, throttle body, and IACV coolant lines (if you have those blocked or circumvented).

My wideband is starting to act strange too.

It's reading LEAN. While the car is running rich.

I don't maybe the problem is my injectors. Maybe they dont like the cold weather?

holy **** thats cold. Move your *** down to florida or something.

What was temps were the car tuned at? The density of 70 degree air and -20 degree air could maybe cause the leaness. I dont know if it would be that great though.

The wideband can't detect the fuel that isn't in vapor form. If it's still in liquid form, it'll just condensate on the exhaust tubing wall and/or pool at the bottom.
