Try scanning the live data for the coolant temperature sensor after the engine is warm to see if it matches actual temp.

Hey, very good possibility that the engine position sensor is failing. Its a bit of a pain to change if it has the same design as the 3800s in the vans. The harmonic balancer will have to come off the front of the engine and you will need to make sure the sensor is adjusted to the proper position when ypu put it back together. Be gentle with the sensor. They are very easy to break. If you have done something like this before seek help. Travis, pro mechanic.
