runs rough when lightly accelerating but fine idleing and heavier acceleration.

Runs fine after a few miles.


I'm thinking the coolant temperature sensor as this seems to be the same problems I had with another truck.


Now, how do you test the sensor?

Best to get it on a good engine capable scanner and read out all sensors readings.
Also check for codes and post back any code no?

No codes on my scanner. Not sure it does every sensor.
