    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.
