    Does anyone know what it would cost to have my PCM flashed? I have a
    pretty reliable local mechanic who can not do it and he recommends
    that I take it to the dealer, he said it could cost up to $600 to have
    it flashed, is this true?

    Thanks in advance

    I got prices at dealers anywhere from $55 to $120 to have the TCM
    flashed on my '99 Concorde - I would assume that the PCM would be about
    the same.

    depends on why you want it reflashed
    if you have a check engine lite thats is affecting emissions then it might
    be done under that
    if you have a service contract it can be done under that if it's a max

    The problem I'm having, as stated by mechanic was that my PCM was
    putting out incorrect readings in contrast to what my tacometer is

    My intial problem is, when my car heats up, don't mistake this for
    overheating, but what I would call normal driving temperature,
    somewhere inbetween the half way mark and one tic below that mark on
    the temperature gauge, my car will begin to idle crazy, high then low,
    then low then high, and sometimes even stall. If I try to floor the
    gas pedal while this is happening, my car won't rev above 4500 rpms,
    instead it gets there and starts falling back a little then up and
    down but never past 4500 rpms. Check engine light comes on.

    When my car "cools" down it runs fine. Check engine light turns off.
    He says he checked all the grounds so he's sure it's not a wire
    problem. He did mention however that when he read the PCM while my car
    was started the PCM read 0 when in actuality the TAC was idling at
    about 750, and then when my car heated up to the "normal" driving
    temperature the PCM would read 10000 while the TAC was showing between
    1000 and 1500.

    He mentioned he had a guy who usually flashes the computers come and
    try to do it but he was unable to because he had to input the VIN
    number and this other stuff that was sort of "dealer proprietary"

    Does this sound like something different than what my mechanic is
    telling me?
