so i put new fuel lines on my truck... primed the fuel system (2 hours later) i fired the truck up and it ran ruff so i cracked each injector till it was spraying fuel and the idle smoothed out. so i took it for a ride and ran great for about 5 min.... now it idles good but if i were to push the throttle pedal in allitle bit and then release my foot off the pedal fast the truck stalls. but it only does it in gear... in park it does not stall at all. any ideas?

 

My truck would do this every once in a while when it was cold out and the truck wasn't warmed up yet. I figured out the idle speed was set too low.

 

bled the system again.... she is running like a champ now.... knock on wood!

 

deffinately make sure the idle is set right; this is a typical symptom of an idle setting that's too low
