its the cold Wx for sure. but for a new one that seems right, i get 5.5-7.8 pending on temp more than how i drive. The mixture gets very rich in the cold temps. I got an Eco meter at a place in Newmarket, it helps.
Do you supply smart parts? Or do you have to send out for your parts? That would be a bummer. Which engine did you get? I'm guessing gas. Pure, Passion, panoramic roof? We have to know these things!
Oh, By the way, WELCOME!!! Glad to have you aboard! Enjoy the ride!
