My 1982 coupe Deville started bogging out like it's not getting enough fuel or it like chokes itself out. After trying to start it up it would not start. So I changed the spark plugs and wires and car started up again, only to die off after a couple of seconds. So I figured I wasn't getting fuel. So I changed the fuel filter and it started but it runs really rough and shakes terrible. Shut the car off and I noticed smoke out the passenger side window. I looked under the car to see where smoke was coming from and the catalytic converter was glowing red and very hot? Don't know where to begin in
