This is my first post, and I'm a new Ford owner. I have 130,00 on the truck. About a month ago, it threw a code. P0128, stuck open thermostat. Did a lot of research, and watched a video if truck doesn't get hot enough it won't go into regen.
I just had both thermostats replaced, when can I expect a regen? Truck runs great, and pulls great also. Has tons of power. Do I need to worry? Hope someone can give me an idea, or am I just worrying too much.

 

Two separate issues there.
