95 Accord EX - 3 sensors go bad at the same time - WTF?!?!?!?!?!

    Hello All,

    I was driving my 95 Accord in traffic, my speedo died, check engine
    light comes one, irratic idle starts, then it over heats.

    Speedo Died - I figure is the VSS - will check this weekend to see if
    I am getting the proper 5 volt pulse output.

    Irratic Idle - took my EACV off, the mesh is complete clogged with
    black stuff, cleaned it, put it back still have irratic idle.
    However, it goes away with the head lights turned on or the AC on. I
    removed the wire connetors from the EACV and the car barely idles at
    100rmp - almost not registering on the tach. Another post said that
    it should idle at 500 to 600 with the wires pulled off the EACV. I
    will adjust the idle this weekend.

    Car over heats in traffic - but when I turn on the AC, the car cools.
    I need to check the fan and temp sensor switch this weekend.

    My question is - has this happened to anyone else??? Is there another
    underlying problem??? Or just coincidence???

    thanks, Phil

    The first half of your description sounds a lot like the ignition switch
    problem... Try searching this groop using google groups. Have you had
    your ignition switch replace as per the recall, or did it qualify???

    Irratic Idle

    Just a wild guess, maybe the ECU has problems reading the engine speed
    causing a bad idle.
    When the headlights and AC are on, the idle rises to compensate and that
    might be just enough to stabilize your idle.
    If the radiators (colling water and AC) are superposed and the fans side by
    side, when you turn the AC on, the AC fan would switch on increasing the
    airflow through the radiator causing the temperature to fall.
    Check if both fans are switching on properly and your termostat is fully
    opening. You might also need a cooling system flush and it is possible that
    with an 8 yo car you need a new radiator.

    On my 1992 Accord EX the cooling fan, not the A/C cooling fan, has a seperate
    fuse. It sits in the fuse box in a position that makes it look like a spare
    fuse. If that fuse is blown or removed the A/C cooling fan will still work.

    Just a thought

    That may be true, it appears that the EACV is working - compensating
    for lights and A/C. And, the irratic idle only happens after driving
    for 10 minutes.

    I installed a new radiator, coolent, and cap about 6 months ago.
    Here's a question:
    1) When AC goes on, does both fan turn on or just the "AC" fan?
    2) When the coolent heats up, does both fan turn on or just the
    "coolent" fan?
    If any of the above two questions are true, which fan is which?
