2002 Vue idle problem with A/C on...

    I just replaced the battery on my 2002 4cyl Vue. Since then I noticed
    that the idle surges wildly, almost to the point of stalling, whenever
    the air conditioner is on. No problems at all with the A/C off. I
    know that after a battery replacement there is a period of time
    required for the computer to 'relearn' everything; but it's been
    almost a week with no improvement. I did an online parts search for
    an idle control valve with no luck, so I don't know if it even has
    one. There are no aftermarket tech manuals for this car which doesn't
    make troubleshooting any easier. On a side note I did notice a good
    bit of oil under the AC compressor last time I was under the car, but
    the cooling is fine. How big a job is it to replace the compressor?
    Thanks for any advice...
