bad mpg what to do?

Correct. It wont be an issue, because if you get a good rate, having a truck with no power is okay. Lets not forget, you're making so much money, that 4.25 MPG is okay in a Columbia. "A fool and his money soon part ways." I make so much money, I call the lot lizards over and pay them to wash my truck and grease it. That's what I call full service. Why? Because I don't haul cheap freight and I have plenty of money to throw around. Now if you'll excuse me I have a game of Three Monte to go play.

 

This always kills me to hear. What you make is abased on 2 numbers. Income and expense. Yes, hauling good freght makes high expenses tolerable, but why not reduce them so you can keep more of that high freght money. Working on one without the other is just a waste of effort.

 

Geez.....just a joke! Calm down people. Now if you'll excuse me, its time for another mint julep. Have a good weekend everyone!

I've had no shakes , normal sound and sluggishness just from clogged air filter. In my experience, when the motor cant get enough air it keeps the mix right and thus derates the motor. it just feels like you cant put the peddle far enough down, but sounds and acts normal.

Since this is the second time i suggested its not electrical, I wont be posting more since i'm on thin ice with the mods for arguing lol. Good luck on getting it fixed. Hope its not DPF, that will be pricy

 

This is good advice, and not just any Detroit dealer, find a good one....

 

Freightliner is the absolute last place I'd take a dpf Detroit. You will wait days to get it in, the guys in the shop will guess which parts to replace and will charge you for every mistaken part they wrongly replace. Take it to the people who know it best, Detroit Diesel. If you don't feel comfortable with what the first place says, thank them and take it to a different dealer and get a second opinion.

 

Could be something as simple as a turbo boost pressure sensor, about $30 for the part, takes about a minute to install.
