I just used my generic $100 mac scanner and all it really does is give you a code and a short discription, so I don't have any scan data available.
But I will look into the ICP (Injection Control Pressure sensor, right?) but I would rather not replace it if its not bad seeing as its about $170. Any ides how to know what it id for sure? Need to hook it to a better scanner i bet.
