I have seen your problem.(because i have a isx too) but i think, but im not sure. the problem might be in the barometric sensor. (ambient sensor)this sensor is in the main hardener of the ecm.(in the button of compressor) its flat square sensor an has 3 wires. but if water, oil dirt get on it, and this sensor has a little hole of air read ambient,(work with turbo actuator you can see a little hose goin to turbo) if the water or hole plugged the sensor act bad. its a possibility that when you or someone washed the motor with a water pressure could have plugged up that hole. if u have laptop(insite) u need to read 20.6hg or less i believe. that for lower than 10,000 feet alt. this makes the ecm act dumb and all sensors and derated afc
