Answer Hi Eric,
codes show you are having massive misfires being detected. Check your wiring and plugs first before you go any further. Gap, connection between plug and wires, coil, distributor ... all can cause this. Could there be a temperature sensor failure ? - its possible. How about the oil circulation?
