This model year V8 had thermostat problems. I recomment replacing that for starters (be sure to remove the bleed cap when refilling coolant but don't crack the housing). There is also a chance the waterpump could have a loose impeller (not as likely but I've seen these with that concern).

The jerking you are refering to is a missfire. Check the plugs but most likely a failed ignition coil.
