I'm thinking it's a fuel issue, also ... don't like the sound of the LP. Crack open the water drain (brass T-handle) at the Fuel Filter manager and have somebody turn the key to on for a few seconds so the Lift Pump runs ... fuel should come out of there without a lot of bubbles in it. If it...
I had a (unnamed nonsite vendor) HO on mine, it was great. Back then, it was like $75. Now, it's $120. I'm pretty sure it was just a Carter HO with a sticker on it, but it did what it was supposed to, and it was flow-on-fail ...most of the Carters weren't, which is an issue for a DS4.
I just...
I had those 2 codes; I cleared them from history, cleaned/reseated all my FSD connections, grounds, new fuel with a qt of 10-30, changed the PMD and never saw them again.
First cardinal sin: impatience. I did all that at once. That means I have no idea which one helped. D-oh.
Start with...
I put the cheapest 30wt in it I could find... no additives, just plain old oil. Stuff so cheap I wouldn't run it in my lawn mower. Bill Heath laughed at me when I asked him if I should switch to something more expensive, said it's all he ever ran in his, too.
Probably going to need to clear the codes with a GM Tech-2 (or equivalent) OBD-II reader... I think that lamp code is in the second code table with most of the instrumentation codes, so I'm not sure if one of the cheapies will do it. Ask Ferminator.
Look in teh 6.2/6.5 Technical Reference Library ... lots of good info there.

Thanks Leo .. I know Dennis was pretty happy with his tunes, and lord knows he is savvy about the fuel/air curves, but it's nice to hear an apples/apples comparison from someone I trust.
Uh, no. At the time, moderators approached you quite professionally and you came back at them like you had gilded poop. Several times, in fact.
We had several fairly intense engagements in the back room, checking with each other to make sure we were treating you 'fairly', and always erred...
Last paragraph is super important.. I saw a guy in Lethbridge not long ago who was really happy with the 'new' chip in his OBDI 1500s ... But his EGR readings were crazy high. I pulled the chip for a peek and under the "Zfactor" sticker was an old Hypertech chip!
Stock exhaust, stock turbo...
Here we go again...
A1 Customs - 'Steaksauce'. At best, it won't work. At worst, you'll hurt your truck.
SS Diesel - you will pay too much for stock parts, minimal gain, poor warranty
Heath Diesel - Top notch stuff, high expertise, top prices.
Kennedy Diesel - like Heath - lots of good stuff...
Trans fluid has been my go-to additive for a lot of years in my chevy gassers, too, used just like he does. Half a pint of tranny fluid in the last tank of gas and the other half in the oil in the last 30 miles before the change. It isn't much, but my oil pans have been spanky-clean when I...
Nope. Well, maybe to the injectors, but not with enough pressure to get Past the injectors. Without the high-energy pulse from the FSD, the DS4 solenoid pump won't compress the fuel down the line.
Without highly-compressed fuel, the injectors won't 'pop'.
I completely agree. From what I know, your cam won't hurt anything; it may not provide the performance jump you are looking for, is all. Most times, performance gains in a 6.5 come as the sum of a bunch of other things, rather than from one upgrade.
As for my comments, I want to apologize...
Good posts, BJ - there is significant difference in having a cam ground for asymmetry on an NA and a FA engine, but I'm also skeptical about the amount of difference. Still, it is a fine line to walk, as BJ points out.
Guys, It's important to remember a few things; Fuel/Air is forced INTO a...
