I ran some cylinder percentages tonight, as I am still chasing a miss, jerk, chug, or harmonic whatever. Checked for codes and there were none. I still love my truck, so I will win eventually thanks to you guys.
Here are my percentages and what do they mean?
#1) 0.0
#2) .2 - .6
#3) .7 - 1.3
#4) 2.0 - 2.6
#5) .2 - .4
#6) 0.0
#7) 0.0
#8) 4.7 - 5.6

Miss, jerk, or chug.... I forgot, have you done anything to your injectors recently? Is the "jerk" one of those things where you're accelerating and you feel a "burst" and a couple of small jerks?

It's more like a consistent jerk while at cruising speeds, and it's very consistent. The chug feels like a huge exhaust leak, but I can't find one and it sounds like its coming from inside the engine. Yes, Jeffreyt and I changed my #4 injector orings since I had it out from breaking a hold down bolt off. I did plug the red line going to the waste gate, was I supposed to unhook some type of sensor when I did that? What next? Any homework? I am supposed to leave for West Monroe next week with my camper, but I don't want to pull it running like this. With my luck I'll end up stuck on the side of the road at midnight with some guy like Shelby from 'Axe Men'. I don't have a grey CPS, I have the one towards the bottom of my sig. It's more of a dark charcoal color or even a dark shade of blue maybe.

OK... I missed a thread, or they're all rattling around in my head - I vote the latter. Here's a guess - you torqued the injector bolts and got a bit gorilla-ish on one?
Whatever the case, it sounds like you're missing a nozzle washer, it's installed backwards, or an injector bolt worked loose somewhere. Looking at the profile of the washer, there is a bump side and a cave side. The cave side should face the injector. Did you notice this detail when installing O-rings?

Hey guys. I'm still trying to figure out why my AE won't read FIPW or my vehicle speed. I contacted AE support and he issued me a fresh copy,11.0.1.,but said there was no known issues with AE and either issue I was experiencing. My speedometer works,but only shows as like .024 on AE, and the vehicle speed status(can't remember exact wording) just shows .0. Anyone have any thoughts on this?..Thanks..Phil

I cry fowl. I could hand these guys a 1/2 dozen different owners that can't get the FIPW to show the correct value without putting in a multiplier of 10, and about 4 guys that can't get speed readings. Maybe I should call them when I'm not remodeling my house, buying a DD, or working on Stinky.

Know this thread is getting old, so sorry. I'm trying to figure out what value to select on AE to check my injector perdels. Getting ready to change o rings on my flatbed, 223k, but wanted to check that my perdels were good. Did the CC test and everything looked good. If someone could post what selection I need to make under the live data grid, I'd sure appreciate it! Thanks

I know I'm late to this class sessions but I'm trying to get caught up.
Here is my data I just took with AE. My truck has not been ran for the last several days and is just sitting in the garage.
I live just outside of Denver with an elevation of 4,984 FT.
The data is KOEO.
Exhaust back pressure sensor is jumping around and spiking at 16.04.
What do you guys think? In case this doesn't show up as a photo here is the data
Exhaust Back Pressure- 15.9
Manifold Absolute Pressure- 11.9
Barometric Pressure- 3.75
