Check your thermostat. It may be time to change that while your at it.
Take your iacv valve off, clean it with out with soapy water and rinse, screw it all the way in when,and then bolt it back on.

Your coolant breaks down and actually "rusts" over time forming large enough pieces of "rust" or gunk big enough to block passage ways through your engine. This then creates a snowball effect with surging/idle problems.

Honda...change the oil and you have a 99% chance to 300,000 miles.
