    Diagnosing shake at idle (not fpr)

    What are the symptoms of air being introduced into the fuel lines? When I did my FPR the rubber lines at the fuel distribution block right there were pretty crusty and cracked, I tried using some tubing from the parts store to replace them but the bends were too tight. I’ve since ordered the...

    Diagnosing shake at idle (not fpr)

    Okay sounds easy enough If it is shot, can I replace it with a single mass and keep what ever clutch is in there now? Current clutch is coming up on 100k but feels fine to my foot. Oh that makes sense. Neither am I. Just trying to learn, appreciate everyone’s input so far.

    Diagnosing shake at idle (not fpr)

    How can I check to confirm?

    Diagnosing shake at idle (not fpr)

    That makes a lot of sense. I was kind of suspecting that. Like I’ve mentioned I have been figuring on doing SAC45s, so it’s not crushing information to hear that. I think I’ll still try AC Delco one more time. With that being said, if all injectors are pretty evenly worn, why would it be...

    Diagnosing shake at idle (not fpr)

    Good question, I forgot to bring that up. Idle is right around 600rpm and if I bring it up to about 8-900 it gets a tiny bit rough and just a little stumbly I feel like. I’ll try and make a video of that. At cruising or freeway speed, I can’t discern any shake over the general rough ride the...

    Diagnosing shake at idle (not fpr)

    My plan is LDS sac45s soon. No white smoke, no fuel halo in oil when I drop it on a white paper towel. Stock. It seems like signs point to the injectors being OK... but I’ll be replacing them eventually any ways.

    Diagnosing shake at idle (not fpr)

    No idea who’s injectors, previous owner said they had been replaced but I doubt they were some quality units or “done right”. 350k miles on the truck. Previous owner said cp3 only has 20k miles on it, again not sure brand or quality of the part that was installed. It’s an old farm truck...

    Diagnosing shake at idle (not fpr)

    02 LB7 ZF6, lotta miles, hard ones too. New Bosch FPR when I got it, really smoothed out the idle compared to now. Before it was lopey, now it’s just shakey. Injector rates don’t seem too bad with EFI Live, and checking with TorquePro app it’s just about the same numbers. Passenger motor...

    LB7: SAC-style Injector Life

    Why do you say California diesel is shitty? Also, at this point, has anyone heard of failing SAC style injectors?

    Checking out a truck with "dropped valve"

    I'm looking at going to visit a guy with a truck for sale that he thinks has a valve or lifter issue. He says he hasn't taken it to a mechanic or anything but is just guessing a stuck lifter. He says he doesn't know and doesn't have time, hence his price. Says it has a loud screech from...

    Diagnosing ZF6

    Thanks, I'll give that a shot

    Diagnosing ZF6

    Sweet! Any recommendation for fluid type/brand? Stock tuning, but sounds like this one might not be me and even better nothing much to worry about mechanically. I thought I was shifting too fast maybe as well, but when cold I've deliberately slowed down and really casually go from 2-3 around...

    Diagnosing ZF6

    I'm pretty green when it comes to the ZF6, so I'm hoping to get some help from the experts here. Having a few problems with mine and want to see if I can narrow it down. When the trucks cold, the 2-3 shift and sometimes 3-4 is pretty crunchy. It's not really audible, but you can feel it goin...

    Need to clear P0101 for just one smog...

    I've got a P0101 MAF MIL popping up on my truck. I need to smog it only once, for a transfer of ownership (to me). After it's smogged, I shouldn't ever have to do it again (rural County) and I'll delete/tune the (Cali) truck. I have: - Pulled and cleaned the MAF and connector - Inspected...

    Ignition Cylinder/worn key

    Thanks for that, hopefully it's not needed but I'd imagine this thing is pretty worn and the jiggling to get it out probably hasn't helped over time

    Ignition Cylinder/worn key

    Thanks for the input, that's what I was hoping. Seems like my 02 3/4 Burb is having the same issue too.

    Ignition Cylinder/worn key

    I've got a very worn out key. With the zf6 I also have the push button on the cylinder to allow it to turn. The button never seems to work and takes some serious finessing to get the key out. Will going to GM with my VIN and having a new key cut fix my issue, or do I need to replace the...

    Fuel tank difference between LB7 and LLY/LBZ

    I called them they were very nice and they were more focused on telling me the way to tell 04.5 split from VIN and that fuel sending unit was different, but also mentioned dimensionally they are different. They sounded like the guy knew his stuff, but he said the current tanks fit '04.5 to '10...

    Fuel tank difference between LB7 and LLY/LBZ

    I'm looking at part numbers between factory tanks and it looks like there's a split where one number is for 01-04 and another for 05-10 I'm debating whether the price is worth it to give it a shot anyways

    Fuel tank difference between LB7 and LLY/LBZ

    Are there physical differences between tanks, other than fuel pickup? I found a transfer flow 45 Gal tank that's advertised for 04.5-06, and I'm wondering if it will bolt up to my 02. I know the pickups are different for LB7, but I'll be modifying that anyways for my liftpump.
