My 1992 Accord wagon, with about 124,000miles on it, "rhythimically" surges about 600 rpms when it is in in neutral or park. It runs fine in gear.

My mechanic checked the coolant levels,vaccume lines, idler valve and everything else he could come up with... and then with a shake of his head, gave it back to me...

Any ideas?

Does it surge hot and cold in neutral? If this is the case, have you had any work done on the car that might have involved the intake manifold?

there is a "cold start" valve located at the opposite end of your intake (from the throttle body),this is often the problem. Another possibility is the map sensor located in the intake or in the black box with all the vacuum hoses to it.
you could also check for an intake gasket leak to.
