If the vehicle is missing, pull the plug wires till you find the missing cylinder. pull the spark plug. it will be clean and most likely will be the head gasket. if no miss, start at the intake gasket. toughest part is the getting at the hose on the back of the upper intake. carefull not to damage the knock snsor.
I would pull the spark plugs and inspect them for discoloration. They will smell like coolant and be very clean. If they are all like that. Then it is possible to have a leaking throttle body. If only one cylinder is like that then it is possible to have a bad head gasket or leaking intake gasket at the cooling ports.
