I have noticed that my trucks engine is pulsing, almost like i have a beffy cam or over sized injector lines, could this be from a dirty injector? I have run diesel clean, and changed the filter, also when the truck is cold like even if its just not been run for a few hours, if you give it like 1500 rpm it will break up really bad. Should i be concerned? or is this common for trucks with alot of fuel going to them? I would almost say its like its not running on all cylinders or its got water in the fuel.

 

Iam sure it has something to do with fuel my does the same thing, with 90 horse injectors and .093 injector lines

 

ya im not sure
