SavageXSS with about 9 tanks thru it. Suddenly in the last few tanks, I went thru a couple of Glow Plugs(OS8) and it keeps stalling if I let off the throttle. In the air or on the ground. Its been running at around 200 Degrees. Other notes: Takes a bit to get it started cold. When it stalls after running it fires up prettty quick. Friend has the same truck and it idles fine and has gone thru no Glow Plugs.This is my second X and my first ran fine.Any Tips or adj to help my problem? Totally stock truck
