    Need help 350 in my 91 caprice runs bad after 4 years

    I had the 350 swapped into the 91 Caprice 4 years ago it was from a 1992 C1500, it ran good the whole time, recently in the winter time it was close to about -30c and I hadn't plugged the car in overnight. When the car started it sounded like a tractor really high idle, I changed all my spark...
