I just had injector nozzles put in by a professional who I trust very much that he totaly knows what he is doing so I really don't think there is any error on his part so try to start looking at other possibilitys. not that I am a mechanic but I watched him pressure test them for leaks @ 4000psi and then he pop tested them 5 popped rite @ 4500 and one @ 4400 the truck runs strong with no stumble at all but at idle it sounds like a v8 with a cam and some times it will stall when you put it in to gear.

 

Are all the coppers in? Any double stacked? Or missing?

I would look there first. Sounds like a high pressure leak.

as far as seeing a leak goes I cant see one. or would it be leaking internally were I could not see it.

 

if its leaking internally watch your oil it will rise and smell like diesel

 

its nozzle lope it seems to happen all the time, the pops need to be closer,
