Odd High idol sometimes.

[6.4 Stroker]

Normally my truck it idols around the 650 Rpm area.
I noticed recently my truck idols slightly higher when driving around town warming up.
It's not much, but it will raise the idol anywhere from 25-75 Rpm higher in drive sitting at a stop light.
I also noticed a slight shake that comes and goes.
I think I might have a weak injector?
Any thoughts?

What are the temps when this is happening? Possibly the Idle vs coolant temperature or Idle vs Ambient temperature additive parameters are active.

I think you nailed it.
It has been cold lateley, and those screeen shot temps look pretty close to when i notice the idol rase a bit.
Thanks for pic!

I wish we had control over this in MCC for the 6.7.
