Hi everyone, I always keep reading this section and trying to give any advice when I can, this time I could use a hand. So it's a 3B, has cold starting issues, and I mean +2C and lower. It is a super glow system and here's what I've done: Changed the glow plugs (with Toy new), rebuilt injectors, recent fuel filter, properly bled fuel lines, changed out Glow timer (with used but working one). The water temp sensor has impedance (can't remember what reading). The plugs get 8.5V (or so) for the first bit then 4.7V (or so) for a lot longer, and continues after the vehicle is started. The issue is that it runs very rough for the first little while, as if not all the cylinders were firing. After it heats up it's fine. I know I could do a Wilson switch, but I just bought new plugs recently and really don't feel like buying another set, so any suggestions are welcome. Thanks I did a search on here but have not been able to find someone with the exact same problem, or I'm just blind.
