Have you had the intake manifold off the engine? If so you may have
not sealed the gasket well allowing an air leak. That happened to my
90 prelude. I replaced the gasket and gooped it this time and it
solved the problem. Other possibility is vacume line leaks.
Good luck.

What was the code??? A P0505 idle control malfunction? It's likely
a bad IAC valve.
