The problem was a radiator that was leaking in the tank on the bottom part of the radiator. I was not losing coolant, but when the system was pressure tested, that showed up. The thermostat the dealer put in last summer was also defective.

Replaced Thermostat, radiator, and water pump. Overheating problem solved.

I am getting a rough shaking idle with the rebuilt injectors I did not have with my old set. I have more power but bad idle shake that was not there before.
