I reset the PCM, no luck came back on; still in fail safe mode, where it deactivates 4 of the 8 cyliners. I read somewhere about a faulty throttle body? Anyway, I guess I will take it to the dealership tommorow.

check it out.....
The cylinder head temperature (CHT) sensor 4.6L, 5.4L:
-is mounted into the wall of the cylinder head and is not connected to any coolant passages.
-sends a signal to the powertrain control module indicating the cylinder head temperature.
i-f the temperature exceeds 126°C (-258°F) 5.4L, 130°C (265°F) 4.6L, the powertrain control module disables four fuel injectors at a time. The powertrain control module will alternate which four injectors are disabled every 32 engine cycles. The four cylinders that are not being fuel injected act as air pumps to aid in cooling the engine.
-if the temperature exceeds 154 °C (310°F) 5.4L, 166°C (330°F) 4.6L, the powertrain control module disables all of the fuel injectors until the engine temperature drops below 153°C (308°F) 4.6L, 154°C (310°F) 5.4L.
DTCs are set.
