Should I pay a shop twice if they didn't fix my problem?

Thats exactly why i have gliders

 

Dealer is a mistake for emissions issues.

You have a Cummins? Take it to Cummins.
Detroit? Take it to Detroit.

There's a lot of diagnostics that goes into it.

Then the ecm also has to be calibrated for your new parts(s).

Lastly they will check to see if something upstream (engine issue) is causing the after treatment problems.

Don't go to a dealer.

 

And if you're in the 700K to 800K mile range, you probably need the SCR replaced and other items if it's a Cummins.

OneBox if Detroit.

I took mine to Cummins. Dude plugs a gizmo into the truck port. Reads the codes on his phone.

This is a pro. He knew what those codes were in an instant.

He's like,"It's gonna cost you some money. "

But they did a great job.

 

Unknown. Seems a bit soon to me. Take it to Cummins. Let them run the diagnostics on it. You'll be many, many dollars ahead.

 

The dude that actually fixed mine has been at that Cummins for 33 years.

The service writer was a wrench for 18 years.

Cummins in Tolleson Arizona.

 

Many parts don’t require calibration.

 

Cummins had mine for almost a week. It's a pretty sophisticated tune process. So I don't see how someone could do that properly in a day.

It's a live and learn thing.

Trucking is the toughest easy job there is, especially when you're honest.
