When the issue is present

 

When it started this morning Temp was ECT 170. IPR was only thing that was any different than any other morning. I've had truck since new and never seen it go that low or stumble. EBP replaced last winter. It wasn't really cold out last night maybe 30. Most cold days it's at 26-28% at idle cold start. After warm it will idle at 22-23%.I high idle my truck every morning before I pull out from work maybe 15 min. And never had a problem.

 

The injector stiction issue. I was under the impression that the stumble or miss I was experiencing was from the drop in the IPR. Does one have nothing to do with the other? Meaning the drop in IPR wouldn't cause the miss or stumble and the injector stiction wouldn't cause the IPR to drop.

 

Ipr controls high pressure oil to the rails. That oil is used to fire an injector if you have a stuck coil it can act as either a blockage or a leak.
White smoke and misfires normally come down to the things I have listed. Suggestions for easy non intrusive testing have been given. Thats not to say you dont have a random odd ball but you now have a place to start.
Your seeing a symptom from you problem.

 

Thanks for your help. Will try it in morning.
