06 9600i international 15L isx... When first accelerating it has no power and then rolls black smoke... yesterday we took off all the piping on the driver's side and cleaned it up real good... It was no help... any advise is appreciated
06 is the cm870...the egr valve is on the passenger side and is a common failure part..I think you have a egr valve stuck open.
Thank you very much for the advise it's a starting point...sincerely, R.T.
This could be many issues. Does it still have the emissions active on it?
You also have an air actuated vg turbo. It can be a leak in the actuator, piping or control module. If you have Cummins Insite you can use it to test the curcuit for air leaks. Visually check to make sure there are no obvious kinks, rubs or broken parts.
It could also be a leak in the charged air system (clamp, hose, the cooler itself cracked, intake gasket) Pressurize the system to at least 20 psi and fix any leaks.
A bad Delta-P sensor and/or clogged cross-over tubes will cause this too.
On a CM870, they are kind of hidden behind the electric fuel pump.
