I've been chasing a random miss in my 2006 for quite some time now and I'm at a dead end for where to look next. Every once in a while it'll have a light hiccup I guess you can call it in gear at idle but most of the time it happens on the freeway cruising. It could be that I just notice it more often when cruising the freeway since the engine sits at a constant rpm and any change or variation is easy to detect. No large puff of smoke that I can tell and it's never constant or grows better or worse with temp. I'm convinced it's electrical.
It has a set of brand new exergy injectors in it along with new crossover tubes (torqued to cummins spec) that only have 8k miles on them by now and were always filtered with 2 micron filters. Valve lash was reset when injectors were installed. I ohm'd out injector solenoids and everything checked fine, tested the solenoid harness and one wire seemed to take a while to find zero so I replaced it for peace of mind. Checked all connections going down to the ecm and cleaned them along with adding dielectric grease. I also checked and cleaned all the ground cables. I've tried running on my stock tune along with all other tunes from my tuner (efi live) and it still persists.
I'm at a loss for where to look next. I used to daily drive the truck but now it just sits and I'm tired of not being able to drive it. Thanks for your help in advance.
