Sorry I haven't been on for a while. I've been busy and my internet went down. I've checked and readjusted the valves. A couple of the intake valves had too much clearance. That may of helped a little, but it hasn't been as cold since I've checked them. When I started it when it was 70F outside it didn't have a miss at all. When it does miss it has some black smoke. Hopefully sometime I'll have enough time to take the injectors out, have them checked, and check the compression.
