Hey guys so I asked on Facebook and I didn't really get very far so I figured I'd bring it up here. 120,000 mi completely stock. Here's what's going on. so with the converter locked and I believe in 5th gear around 1500 RPM I randomly get what feels like a misfire when applying light throttle until the turbo spools up. I bought this truck from an auction all the glow plugs were bad replaced all those. The truck had some dead battery issues right before it went to auction so I looked at the stored codes but ended up clearing them because a lot of them were communication codes which would be related to a dead battery. All filter replaced, all fluids (except trans and xfer) replaced. I meant to write down the actual codes but one of them was for EGR and the other ones was for glow plugs. I've replaced the glow plugs everything is completely fine as far as that goes. the filter head does like to lose a little bit of prime overnight so if I just fire it up first thing in the morning it'll run a bit rough if I put about two pumps onto the primer it runs completely smooth after start. I have conflicting data from different scan tools some of them are showing the EGR experiencing large error % as far as deviation. My all tell is showing small amount of error (2% at idle) but not enough to trigger a code. Doesn't feel like 605 torque if I'm honest. Pretty sure my 8.1 could out pull it at this point. Here are the fuel numbers Attached is some OBD live data First few are some screen shots. The one with the date is the most recent. Here is a link to the EGR doing it thing last week while I drove around town. Big drive south (AK to AZ) supposed to start tomorrow night. But I don't want it to brake down in the middle of nowhere.
So recently I cracked the bell housing to my transmission and it lost all the oil, so I’ve been looking at good used transmissions. My question is what years are compatible with the 2006s? I’ve heard the plugs vary year to year making some incompatible with different years. Any advice would be awesome.
Hello Anyone. i have a LBZ Duramax, and i have just put in a new water pump and rebuild the oil cooler and the pipe that connects them i put in after and i pitched a gasket and it eakd then i took it out again and put two non OEM gaskets on there and it seemed to stop leaking when i added coolant but when i fired it all up it pissed out again so my question.. what is the propper way to put the pipe in, i could no imagin putting it in the cooler then putting it back on the truck, do you put it on the water pump first maybe then put it in??? or can you some how use gasket maker instead??? i need help
This question has probably been answered on here a hundred times over but I can't seem to find any search results that match exactly what I'm looking for. My dad has 07 Classic with the LBZ Duramax. He absolutely loves the truck and plans on running it til the day he dies. With that being said, his biggest complaint is the fuel mileage he gets out of it. He averages 12-14MPG no matter how he drives it even when towing our boats/campers. He keeps sending me links to sketchy sites with tuners that are dirt cheap and claim to greatly improve fuel mileage. I'm smart enough to know not to go cheap when it comes to tuners/programmers. Can anyone provide any recommendations on somewhat affordable tuners that increase fuel mileage enough to warrant buying one in the first place? Or any other ideas to help squeeze some more MPGs out of it? Any input is greatly appreciated!
