Ok my truck does this stuff of dien when you let off the pedal to quick. I have the idle set at 850. It used to only do it when cold but now does it all the time and it so anoying. It dosent die like if you are driving and just let off the pedal. It will die when you are backing up and let off the pedal to fast. Or if its in park and you like bump the pedal it will reve up and insted of catching itself at 850 it will just die its like it super cold natured all the time. What is wrong with my truck?

 

my truck did the EXACT same thing even with my idle set right. so i put a different set of injectors in and it hasnt ever done it since. i guess these injectors just get worn out after a while.

 

i see it has 3k gov springs sounds to me like they are not adjusted right at least that
might be a place to start if it started doing all that after the springs was installed.
could also be getting air in the fuel line check return line back of engine
i know mine died all the time till i got the springs right

 

How do i know if the springs are right?

 

the trans can cause this problem. good luck with it

 

I keep adjusting the idle but its like it just keeps going down

 

 

try the spring on your throttle just for a start imne did that when it was starting to wear out
