    My check engine light came on and a ran a test which CARMD told me
    was: change Barometric Pressure Sensor. What is this for? what does
    it do? and what happens if I don't do it now or for a while?

    This sensor just fine tunes the mixture according to the ambient
    (barometric) pressure. If it's bad (or there's a wiring problem) the
    computer assumes a standard value, and other than the check engine light
    you won't notice much change, and it probably won't hurt anything.

    Replace tt with t (twice!) and remove parentheses to email me directly.
    (But I check the newsgroup more often than this email address.)
