my truck idles rough with these injectors, the guy i bought them off, needed to put shims in cuz they were popping off at too high pressure, This morning i started it up, idles perfect. then after work, ran fine until it got to opperating temp. then it started stumbling again. it doesnt do it under throttle only idle -1200 rpms
a lil help

i have read that these engines will sometimes "lope" at idle with 150+hp injectors, but it seemed it was aimed towards the extrude honed not the EDMs. Im interested in what others have to say.


sorry i couldnt be of more help, Pat

Is it a miss or a lope? Maybe your injection pump is trying to tell you something. I'd have the injectors tested and see what they pop off at.

I'm guessing these are NOT from Don M??

"jammer-5s" in the sig. seems to be DD.

Meatball

no, money is tight

Meatball

whats a lope, it sounds like a miss, but its not that bad, hows about a stumble?

Meatball

yes DD, nozzles

pmtg

just the nozzles? have the injectors cleaned and pop tested.

Do you have stock tubes, or oversized ones? If you have oversized, try putting stock ones back in.

I would go back and make sure everything is tight. Air seeping in from a loose connection is a bad thing. If you didn't have the pop pressure checked and set you need to do this. My jammer5's idle smooth as glass. Don's injectors are good, but, don't let these other guy's make you think they're the only thing out there, cause there not.

thanks, yes i had them pop test before they sent em out, they were popping off high 4500 i think? but he got a shim kit and got it down to normal pressure. It stutters under acceleration when i turn the comp box on too. Im gonna get down to the shop next friday. Now sleds this is my first time so maybe i have a loose connection. the only possible think that could be loose is the injector line nuts, im gonna go out and check em. OBI- these are stock tubes. Sleds, shoot me a PM, id like to talk to ya sometime about these.
Your soot-shootin' buddy,

You'd see a puddle of diesel under the truck when you park even if there's a slight leak. I have slight leaks (~4" puddle when I park overnight) and zero troubles with 223 hp injectors lopey or idling funny. Of course, mine are name brand injectors configured for my truck in Texas. I think you get what you pay for- IMO. Did the injectors flow within a percent of each other when tested?

So, your sayin edge and dieseldynamics are not name brand eh?

Meatball

first off brandon, spell your name right. haah, second off, i do believe you get what you pay for, i did alot of research before i bought them and i didnt see any glitches, maybe im the one in a million....we'll get this cleared up next week.i think they need another pop test. Hey sleds the highest i got my pyro up to was 1300 on a long hill, comp level 1. on a flat stretch today 0-100 comp 5x5 i got it up to 1194* is that crazy or what.....maybe my pyros broke heheh.
