I have a problem on my 2000 that has a 3 stage chip the connection either comes loose or gets a bad connection and will start shutting down going down the road. I switch to stock and runs fine until I can wiggle the connection
I have the same problem as you so I am getting the B100 then mixing my own ratio. Have had no problem with filters clogging. I thing the biggest problem is with the people that don't change filters that often in the first place. The only problem i have is the trucks seem to be getting harder to...
If it gets down below 40 degres you better run a b20 or it won't start.
Had around a b 40-50 mix last fall pulled the truck out of the garage let it sit for a while and would start until I warmed it back up.
Just a thought here.If it was a glow plug it wouldn't be smoking black would it? Glow plug would cause a cylinder not to fire right off the bat which would cause a greyish color smoke not black.just my $.02 -popcorn
