Symptom: rough running at quick stop (but does not stall), CEL is on, and P0401 error code !
1. I checked EGR valve...depress back and block tube in front - held suction! GOOD
2. I checked all tubes for leaks, burns, etc. GOOD
Q: Is there a way to remove and clean EGR passages!! I researched youtube, internet?? no luck??
I pulled tube from top manifold to the valve cover...had carbon build-up debris (flushed tube) seems to be good suction from top manifold?? orifice on valve cover port?? is there another tube for the other valve cover?
Thanks for any comments
