Hello whenever i run my truck for a while and then i come to a stop and at idle it kinda has a sound like its missing for just a second and also when i have run my truck for a while at idle my fuel pressure is around 20-21 psi at idle whenever i have ran my truck for about 15 minutes or so what could this be?

 

https://www.dieselbombers.com/24-val...even-idle.html your pressure seems to be okay should be between 18 and 24 psi and you can check this out

 

Sounds like dirty injectors,or worn injectors these are a wear item in time the spring gets weak after a while.Fuel pressure sounds good at idle.How many miles is on the truck?Is there any mods done to it fill out your sid.

 

my truck has 205,000 miles on it and the injectors are not stock they came with the truck and their 65 hp injectors but the guy did not say what they were. and a fass ddrp pump but no chip yet.

 

I had that exact same problem turned out to be my injectors. They were stock bought some 60 horse injectors and the miss went away.
