    My wifes 96 Accord EX V-6 runs rough sometimes at cold startups. Seems
    to smoke like it is running a little rich till it gets warm. Car has
    150K miles and has been well maintained although wires and cap\rotor
    have not been replaced to my knowledge. I was told wires on hondas very
    seldom go bad. There is no check engine light coming on. (Bulb does
    work) Spark plugs are new NGK.
    Would a trouble code be stored even if check engine light does not
    come on? Should I replace O2 sensor?

  2. ==========================

    One of your injectors is leaking down the pressure overnight. Since it's
    a V engine, it will still start, but blows a bit of smoke. If it was a 4
    banger, it would not start at all unless you hold the pedal to the floor
    while cranking (see owner's manual - flooded engine).

    The best thing to try is a can of Techron injector cleaner, or do what i
    did. Run a few tanks of Gasohol through it. Don't let some clown sell
    you six new injectors.

    what kind of gas do you use? seems like you guys have a lot of problem
    with the accord.

    my 99 accord was running strong even with supercharger.
