dude, start the engine to see if you've fixed the problem first!!! if
not, /then/ worry about the code. and if replacement doesn't cure,
check the wiring.

also, make sure your coolant level is correct.

Definitely, start the engine. The ECU can't know whether the IAC valve is
working until the engine is started. If it idles okay and the light is still
on, drive it a while or reset the code manually and see if it returns.

In the unlikely event the ECU is bad - they rarely fail unless they get
wet - a replacement usually costs about $75 to $150 US at a wrecking yard.
Prices vary that widely, so call around. It should come with a 30 day
replacement guarantee in case of an intermittent. If it works 30 days it
will probably work forever.

BTW - where is this located? I think all of North America was using OBDII in
1996, and 14 is the OBDI code for IAC valve signal.

Hmm. I think it's already OBD-II, but the CEL light is on so we jumped
the SCS connector, and the CEL blinked one long and 4 short blinks. Am
I reading it correctly?

Start the engine. Does it run OK?

What country are you in?

Ah - I heard there were some versions that could be read as either OBDII or
OBDI, and this must be one of those. That should be the correct reading.
There is a manual for Japanese import OBDI reading at
http://www.iequus.com/downloads/manu..._E_14JAN03.pdf and Hondas
are on pages 16-25 of the PDF.
