Miss at idle only when engine warm

Those really don't look bad for the amount of miles. The best way to keep carbon from building up is getting things good and hot. If you can get the EGTs over 1000 for an extended period it should burn the carbon off. I regularly get mine into the 1300+ range and have never pulled a set that look dirty (I've had 3 sets of injectors in my truck)

 

As for torquing I wouldn't worry about it. Tighten them up so they don't leak and call it a day. I've never seen anyone use a torque wrench on them and never seen anyone have issues. If it's leaking tighten some more!

 Cant add anything to that.

Be careful. Like @JAG1 called me today because he's got an injector line that is bleeding fuel some. He was doing the same thing and was smart and stopped tightening the line more and called me. You have to be careful and check the line to socket for debris and be sure the line is fitting good and the taper is sealing good. All it takes is a small grain or sand, rust, corrosion, or metal sliver to keep it from sealing and just cranking down hard it going to crush that debris into mating faces.

Yes, I used 600 grit emery cloth on the high pressure line tip. Placing paper covers over the three disconnected injectors to keep debri out, I  lightly squeezed the paper to the tapered bottom portion and go around. Don't go up and down, go around with the circle on the tip. Then with a flash lite and mirror, check to see if it nice brite and no defects. I did find a very small defect, about 1/4th the size of a pin head (very small) I used the emery again till it was gone and thanks to Michael Nelsons advice, it doesn't leak now.

 

 It's key that you don't keep tightening those H/P lines if you have a stubborn leak you can ruin them. Snug not wrenched is how I can best describe it. My leak was stubborn and I knew not to force it so I refinished the surface is all.

 

I learned about the emery cloth on this forum. Been here for years and still learning from you guys. Thank you all.

Mine stopped leaking after the last round of tighten, but each time only tighten a bit more. If it continued to leak weep then i would have, checked mating surfaces. But so far it's sealed.

 

again thank to all the awesome help from this site.
