Where I live we see -30 and below for days/weeks at a time. Fuel injected engines do much better in those conditions. I haven’t had to do anything but oil changes in the last 10 years on my vehicles, no chasing sensors or anything. And if a sensor does go bad, the computer will tell me exactly which sensor it is and boom it’s replaced.I dont get all the hate for old cars with carbs. My carbureted vehicles honestly require less fiddling and chasing sensors. The most I ever do to carbs is adjust the idle every 6 months or so. My eagle has a 38 weber takes 1 pump and starts immediately. My old van had a cheap holley and i only adjusted it once in 3 years. The demon on my maverick took a lil bit of work because i bought it at a swap meet. once it was cleaned up I would fiddle with it maybe once a year in spring.
I dont expect carbs on new cars but dont get the pure hatred i hear all the time. They are about twice as hard to deal with as a doorknob.
