Hi guys I have a 99 Civic and in the winter only it will idle
really low after driving for over 10 minutes. When I stop at
a red light it even stalled 3 times last winter. It never happens
in the summer though... only in the winter. I sprayed the plugs
and cap with water like someone told me right when I start it
but it didn't make it idle low... only after the car warms up it seems
to happen.

Then if it stalls or I shut it off... then turn it back on... it's fine...
for
another little while.

Please fix my car =)

I have the same problem with my '94 Civic. The colder it is the lower
the idle speed (after warm-up that is). I don't know of a real fix, but
turning on the headlights seems to bump up the idle enough to make the
car drivable. There is an ELD (Electric Load Detector) in the under-hood
fuse box and when the ELD signals the ECM that the current draw is over
a certain threshold the ECM bumps up the idle speed by about 100 RPM.

AFIK, two things: The EACV may need cleaning/broken, or the signal required
to tell the ECU that tells the EACV is inactive. Another words, the ECU gets
a message from sensors but ECU ignores message and won't response to the low
idle's request. However, the ELD circuit appears functional.

This might require troubleshooting the EACV, ECU, or sensors. Unless you
have proper tools, I would suggest cleaning it or tap on it and see if it
budges.

Thanks guys... any last thoughs I could try myself
without getting ripped off at my local Honda?

No last thoughts, but please let us know what you find out!
