I have a 99' Honda Odyssey and when I have had the trouble codes read at autozone there are three codes and 2 appear twice exact same codes twice. the ones that were appearing twice were a EVAP leak code and a egr flow code. I have replace the egr valve and cleared out the port of the buildup. after that i had it scanned again and rather than having 2 egr flow codes i only have one. the evap was fixed but not enough time has passed to ensure that it is fixed yet. So my question is why are codes showing up twice?:huh:
