Cummins ism - Truck242 - 08-01-2019
Good day all what can I do to get my ism to run better. It runs and sound like the turbo doesn’t know if it want to be open or closed so power is never consistent. Any help or advice would be greatly appreciated.

Do you have a check engine light on? Is it demandated? How many miles? Do you have insite and an inline adapter?

Yes cel comes on and off but it’s egr related. I have insite 7 and nexiq link

maybe start by pulling all the EGr piping apart and cleaning it out + replace all sensors related to it.
Change intake sensors as well.
