Got this code this morning when I took off from the house. I floored it and truck stumbled , red lighting bolt and cel lights came on. Did I not let the truck warm up enough :confused013:

Crankcase regulator valve performance.
Correct, but all the crankcase regulator is a ball check valve with a spring. So I wonder if not letting the truck warm up caused too much blow by and temporarily overcame the spring :confused013:
