I have a 2000 accord coupe V6 that was involved in a small front end accedent and sat for about 6 months. I put a new battery cable on it and fired it up and it ran just fine for about 1 minute. from that point it starts to surge 1500 RPM or so. Seems like a vacuum leak. I have looked and do not see any hoses that are damged. can someone point me in a direction to trouble shoot out? I disconneded the idle control valve and it did not change. Thanks in advance.

I believe it is for different year model Accords, but the concept is still the same.
Search around the forum, there might be more on this issue out there than the link I posted.
