Sorry if this seems dumb. This code, P0670 just popped up. I can clear it with my CTS. It stays gone until I shut off the truck and then comes back up when I start the truck again. My understanding is that the glow plugs assist in warming the combustion chamber for start up and that is pretty much all. I have a trip coming in a couple of days. I do not have time to get into this. So my questions are these 1. Am I correct on the function of the glow plug system?
2. Any adverse effects for running 1000 miles with this code?

I am pulling my 25 foot boat to Lake Powell and then back.

Thanks in advance for your comments.
