2000 Honda Accord V6 Idling Issues

[George_San_Jose1]

I think I recall some model year of Hondas have had a recurring problem with the fuel injection system relay or fuel pump relay. Something like that. Usually the symptom is the car won’t start, then if you try later it will. But OP’s symptom could conceivably be related too. OP should ask shop about that, and if that’s a possibility it is probably worth it just to replace that relay. The relay is probably less than $20 and it’s an inexpensive experiment which just might help.
