I happened to notice that 9/12 of the tanks immediately following cleaning the EGR passages were a couple of MPG lower than before. Did it take five thousand miles to reprogram, burn out the carbon, or something else?
Maybe Seafoam after cleaning the EGR would be in order.
Also, I just reported someone cloning the first 110 words of this in a new thread, and never posting again.
People on the Internet are weird!
