Found the following tip on a rather obscure site... it's a troubleshooting search engine if you will.

HONDA IDLE PROBLEMS
92-95 CIVIC, DEL SOL
Major engine work can be a long and tedious job without having subsequent driveability problems after you’re done. But if you experience idle problems after
doing major engine work, here’s a tip that can save you a lot of diagnostic
time. If the vehicle exhibits a surging idle after it warms up, check for code #
14, which is for the electronic air control valve solenoid (EACV). If you have this
code, you may have crossed the connectors for the EACV with the Purge
Control solenoid valve. These two connectors are identical in shape as well
as being very close together in the engine compartment. The best way to
identify the connectors is by using the wire colors to differentiate them. Both
connectors have a yellow wire with a black stripe, which is the power feed
wire. The EACV has a blue wire with a yellow stripe, while the Purge Control has a red wire. A simple repositioning of these connectors should alleviate the idle
problem.
