Hello everyone, really hoping someone can help me out here, I've got code P0236, high boost at idle on my 95 powerstroke. I replaced the MAP sensor and hose and made sure that the port on the manifold is clear but I'm still getting the code. I verified ground on pin A, 5 volts on pins B and C of the MAP plug. CEL comes on as soon as I back right off the throttle after having decent boost. Engine runs poorly for maybe 30 seconds and then it resets, light out, running normally. I have to make sure 250 mile trip home tomorrow and I'm not sure what else to do. Thanks.
