Hey guys. so my truck wasnt starting, narrowed it down to the glow plugs and replaced them. after 3 days of my truck not starting, it started up with ease. I was letting my truck run and warm up for about 20-30 minutes and my truck sounded like it wanted to stall. i turned off the truck checked the fuel bowl to see if it was getting fuel which it was and started the truck up again. idled fine for 5 minutes and started doing the same thing again. i have no clue what is going on. any help would be great. thanks!
