Thank you for the reply. I just replaced all the injectors and the ECM. Do you think they forgot the graphite washers deep in the injector cup and...
Hey Guys, 1999 Detroit, Series 60, 12.7 : Recently started smoking A LOT on startup only, with stumbling idle. Then runs great after 30 seconds....
Awesome reference, but I think it's for DDEC5. Gonna dive into it more later, but yes, the plug on the rear fuel filter housing has a plug, same...
Thank you so much for the quick reply! The harness does hang right at the front of the rear fuel filter and is long enough. I think I will get a...

Hey Guys, Need help identifying dangling sensor off ECM wire bundle. Pics attached. Sensor runs to front lower ECM plug. TY for any help.
Yeah I need to check this. I think this is what Wore Out was talking about, so I'm foresure gonna look for a puff or fog of white smoke. Thanks...
OK great insight, I will look for a white puff of exhaust next time I hear it. I'm gonna pull the stack/muffler also to make sure the rusted out...
OK now that you mention it, I have noticed a "movement/vibration" at my feet on the floor. Thought it was a worn shakle, but I will check the...

Will do, that sounds like a good starting spot. Thank you.

I stopped by Freightliner and the Service Manager agreed that it sounded like the parameters were set up with Reward Specs. I will bring the truck...
Hey Powder Joints, what’s that mean please?
That sounds almost exactly what’s going on. I typically run 2 roads from Shreveport, LA to Lubbock, TX. The truck starts at 67 mph, after 15-20...
This could be it, even though the MPG is about the same as before when I was doing 72 constantly loaded/empty. 6.3 mpg previously / 6.5 now.
That’s what I was thinking, but it only gets to 72 when bobtail or rarely loaded. Seems like if it was missed programming, it wouldn’t get back to 72.
Yeah, so I wonder why I can only go 67 MPH right after starting truck, but occasionally 72 MPH after a bit. I changed TPS, didn’t help.
