Its just as cold in manitoba. Havent had any issues. Do you have an interceptor to check codes?

You should invest in one. It's your best friend once you start modding. Plus it can help the people on here help you much more knowing what codes are coming up

I bet it's o2 sensor heat code. My car does it when it gets cold. Works fine as long as it's warm.
You really need a code reader to answer your question though.

I use a code reader so I can get freeze frame data too. I seldom use interceptors to reset codes, (only when I know whats wrong)

And yes
