I took out the 200hp injectors and put 100hp injectors in and have had a miss once the engine warms up, when the engine is cold it runs smooth. Injectors have been pop tested and I reinstalled them just to make sure I didn't miss anything. I haven't changed the fuel filter that goes from the tank to the FASS(without filters) but I changed the stock one when I did the injectors. I don't know what the fuel psi is cause the sending unit took a dump, so I have a mechanical one on the way.

Any ideas?

good luck with this one I have had it forever comes and goes when it pleases change injectors and all no change

Whose injectors are they? I have had four sets that do the same thing but have also ran injectors that don't do it. It only misses when the motor is running warmish to hot. My jammer and BD sticks both do the idle miss. My formula and DPP sticks don't.

Dynamic diesel, DDP 200 and 275s ran smooth as can be...

does your idle rais up slightly when it does it? I can turn on my ac and it goes away.
