Low ECT and EOT

I have a 2005 6.0 diesel in my shop and autoenginuity is telling me that both are about 120 degrees F. Both with in 5 degrees of each other.

Question-could the thermostat be stuck open and not heating fast enough?

Also has an error code of P-0266 injecter #2.

Buddy's truck-complaining of running ruff and this is the codes I pulled. Nothing for the under temp condition.

He says it will start laying down and he will cycle the key off let engine die, turn key on.....roll drop the clutch and restart and it will be fine for a while.

Checked with autoenginuity FICM voltage and it shows 46-49 volts at all times.

There are other parameters with the FICM that you can select with the autoenginuity and they are showing red at 13.5 volts.

Any help would be appreciated.

Adrian

Not considering the #2 injector I would block off the radiator and get the temps up to normal and see how it behaves. The thermostat sure sounds like it's stuck open.
