0 Joey Mack Posted January 23, 2022 Share Posted January 23, 2022 (edited) the steel pipe from the compressor tends to build up with carbon and blocks the flow.. i bet its restricted.. you may be able to take it out and throw it in the firepit and burn it out, or just replace it.. its expensive, and hopefully still available.. lately, common parts are a bitch to get... jojo Edited January 24, 2022 by Joey Mack Poor spelling Quote Link to comment https://www.bigmacktrucks.com/topic/69100-mp8-help/page/2/#findComment-487763 Share on other sites More sharing options...

0 67RModel Posted January 23, 2022 Share Posted January 23, 2022 I'm willing to bet that truck is coal hauler in West Virginia or Kentucky. Most of the coal haulers from that area run trucks like this. Enormous beds on tandem axles with spokes.

This engine being deleted we have no idea what the program is doing in that area? Try unplugging the EGR valve and see if this changes your situation! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69100-mp8-help/page/2/#findComment-487778 Share on other sites More sharing options...
0 Ox50 Posted January 23, 2022 Author Share Posted January 23, 2022 I have closed the egr valve using premium tech tool while it’s running seems to me like when I do it runs like crap so I was thinking it was good to go I went out this morning and see antifreeze laying under the truck coming from the exhaust system Quote Link to comment https://www.bigmacktrucks.com/topic/69100-mp8-help/page/2/#findComment-487794 Share on other sites More sharing options...

Being deleted we don't know what they have done to this programing! Remove the egr hose front of the EGR cooler first cause its easy If it is soaked you have your answer ! Then check the injector, if the cooler is OK!
