Codes and idle S70 1998

The check engine light on my 1998 s70 turbo (68,000 miles) has come on. The code reads P0108. The car will start, but I have to keep my foot on the gass to keep it running. I ordered a new MAF, thinking that's the problem - but now I'll not to sure. Any ideas?

Thanks

    Codes and idle S70 1998

    Manifold Absolute Pressure/Barometric Pressure Ciruit High Input. On our cars, I believe this is the circuit on a triangular mount right in front of the over-flow tank and windshield washer cap and behind the passenger side headlight. Not sure what the cost or the part number. Also, doesn't mean the circuit is bad...it just that the ciruit is reading a problem. This is what controls engine function at below or above sea level. Did you make a trip that accounted for such a thing...mayb Denver or Death Valley? LOL. I would reset the code and see if it comes back with a OBD-II code reader.
