    Just got the MAF sensor replaced and fixed a stalling problem, but still have a pretty rough idle. It threw a P0108 code on the way home today, MAP sensor High Input.

    Here's some freeze frame data from my scan tool.

    ECT - 96 C
    MAP - 103 kPa
    Engine RPM - 883
    Speed - 0
    MAF - 5.31 g/s

    This code was thrown at idle. I looked around and 103 kPa seems high for idle?
