I have 2000 V6 honda accord.

1: in the morning when i start my accord it turns on fine or when i start it the first time it starts fine when the thermostat is cold.
2: it give me problem when i park my car for like 20 mins or so (when the thermostat is still warm)after driving it for sometimes. my car rpm flutters and it shutdowns and i have to push the race for a while to keep it running. i went to autozone and they said all the cylinders are miss firing. i changed my spark plugs but the problem is the same. whenever i start the car when the thermostat is cold it turns on fine or even it turns on fine when i just shut it off and turn it on. please help me out.

What kind of spark plugs did they sell you? Hondas like NGK best, Denso OK. They dont seem to like Bosch, for some strange reason...
