Hey Mafia,
Do yous guys let your cars sit at idle to warm up in cold weather (I'm talking below freezing)? My fiance always lets her car do that, as do many other people, but I've always done what the manual says and just start the engine and start driving. I've heard it's bad to let your car sit and idle since it'll foul the spark plugs. In fact, she saw on the news today that some car shop owner said to let your car sit and idle in cold weather for at least five minutes before driving off.
What say you, Mafia? Do you start and go or do you start and wait?
