SERIOUS power issues w/ my Detroit14L

get ahold of Rebel127 on this forum he can fix you right up

 

Boy I tell you, nothing gets me more fired up, then having the dealership tell you, " I cant find the problem", But your bill is ready for you.

Wish I would get paid to have Tried....

If you want to continue to have independent shops.



And in the end, it would seem you might be a part of the issue. Demanding the shops to find something wrong.

I have been on both sides of the counter. It's frustrating for all parties I know. Get in touch with rebel127 and just let him do his job. Don't offer anything unless he asks. But give him a well written statement to begin with.

 

Has anybody carefully examined all of the OEM wires in the harnesses???

If you want to have one of the best tech's in the US look at it take it to Atlantic States Detroit Diesel in Middletown CT, talk to Pete or Gary in service.... These are the only guys who touch my truck, and they're good.....

First place you start with these Detroits is the wires, almost all of the problems with them are wiring, not parts like sensors and what not..

That being said...

You might want to pull the turbo boost pressure sensor out of the intake and see if it's sooted over. (These egr motors tend to soot over the opening in the sensor, it seems to happen somewhere around 175k in mileage on the sensor...)

A sensor will run you about $35

I replace mine myself about every 175k or so....

You'll get an erratic turbo boost, (with loss of power down low, like you're saying), with a sooted up TBPS

 

If you do this go to Lowes and get a socket that fits the sensor body snuggly, it's a pretty big socket, an inch something I'm thinking from memory, anyway, c a r e f u l l y disconnect the wire harness from the sensor and remove the old one with a socket wrench, check the opening in the sensor to see if it's obstructed with soot.

Hope I've helped

 

Nope, the delta p sensor is a deleted item. (it can be removed from the system, they delete it and close off the vacuum lines) The turbo boost sensor is located right there by the valve cover where the injector wire harness comes out on the drivers side and runs down to the ecm, it will sit right next to the plugged hole for the ether cold start option....unless you have that option installed.

 

you can find them in this document.

Have you opened up your wiring harnesses and seen what they look like inside? This is what mine looked like. Replaced the ECM to Firewall and it's running much better.
