I have a 0401 code and I have already replaced the EGR valve, ran cleaner through the system and about everything else. I have been told to clean the "pipe" and the intake manifold area of the sludge/carbon. Outside of running through a cleaner again, how do I do this? Is the "pipe" the pipe that comes off of the EGR valve? Thanks.
