Mine sound just like yours but worse. What oil are you running?

Ok I got a update. I took if the driver side valve cover and did some inspection. All the injectors were flat (used a level). I re torqued the valve bridges 20 ft pounds. About three were loose (barely) and re torqued my injectors 10 ft pounds which is 120 inch pounds. ALL my injectors were loose! Some quarter turn some 2 turns.
While I was there I did the quarter mod. The plug was unplugged a hair so I put the valve cover on threw 4 bolts in starter her up warmed her up and it still has the funky idle but it idled much quieter. So I'm going to do the passenger side next and will write back.

Sounds like you're on to something....get back and let us know how it turns out.

I run rotella 15-40. I was running valvoline 10-30/40. It seemed to smooth out after I changed oils.

Thanks, man....that will be a great refference that I haven't been able to find anywhere online.

What would you guess would be an estimated time on taking the valve covers on and off?

He's got stage 2's. Hard to pinpoint an idle issue running on stock programming that way.

He's already replaced sensors. We may be fighting IPR duty cycle problems at this point....not uncommon, but usually close enough for the thousands of trucks that are tuned daily.
