EGR flow
2001 Accord V-6 coupe. The computer keeps throwing PO401 insufficient EGR flow. Checked stock valve per manual, OK. Replaced it with aftermarket valve, no change. If I run Lucas fuel treatment it'll stay out for a couple tank fulls. Is there a modification I can make, or can someone point me to a thread that deals with this problem? When the check engine light is on, other lights come on and off eg. TCS, SRS, side air bag, brake fluid. As long as the CEL is out I don't see them, and no codes for them.[:@]

RE: EGR flow
Sounds like you might have a carbon problem in the EGR passages or also maybe the EGR solenid is defective...
