Hey guys I'm curious what the symptoms of failure are for my stock sticks. They have 125k on them and my truck seems to surge lightly on idle and almost miss a little bit at hwy speeds. Let's a good puff of blue smoke on startup buts god away almost immediatly please help me! Thanks also if seems like my power kind of went away but I can't say that for sure! Thanks

Blue smoke at start up is possibly valve seals leaking.

 

Typical injector failure could be all kinds of things. Miss at idle, surge or lope idle, maybe none the above. Ive got my OEM injectors which run fine, idle fine, no surge or lope. On the pop tester they are popping at 240 to 260 bar. New injector should be 310 bar.

 

For sure bet either send them to be pop tested or replace them.

Could also be electrical issues for surge problems
