I think I'm going to pick up an infrared thermometer from HF, start the motor and check the temps on each cylinder. This should narrow it down. Assuming I can narrow it down to one cylinder, then I will pull the valve cover, start the motor and unplug the injector to see if it stumbles or if there isn't a change. If no change, I'll look at replacing the injector.

The valve covers have 2 connectors on each cover. There are 2 glow plugs, and 2 injector connectors in each connector. You can have a single injector connection fail inside the valve cover. You maybe able to use an OHM meter and read the resistance from the injectors to ground.
