What's the best way and or cheapest way to fix my 1997 Honda Accord EX v6 PO401 EGR flow fault? Can the EGR valve be cleaned instead of replaced or could a vacuum leak cause the fault?

The ports are probably clogged and need cleaned out. You will probably have to pull the intake manifold and clean them as well as the EGR valve. Common problem. Do a internet search for lots of info.
