Weird things with engine light
Playing around with the Scangauge 2:
Temp 48 degrees.
Got the romps couple times but then started.
The idle jumped up a little I guess because to lower temp.
While the idle increased, engine light went off (right after the rpm jumped up).
Engine light off until I press the throttle just a tad and the light came back on.
Idle then stayed around 600 but fluctuated just a little to 700.
No codes on Scangauge.
Here are my readings from Scangauge
Are readings in normal range?

It completely depends on the EOT and the tune. You will get about 700 PSI ICP and 14% IPR at idle with a cold engine on a stock tune, and about 500 PSI ICP with about 10% IPR at idle on a warm engine with a stock tune. I have seen 575 PSI ICP with over 11% IPR on a chipped truck at idle when warm.
Romps - cold weather, old injectors and 15-40 oil are a recipe for romps. Synthetic oil (5W-40) is a common cure for cold romps on aging injectors - but other things can cause this as well.
