I have recently pulled the motor and overhauled it because of the heads leaking. I have currently got everything running was getting a p0385 code which I have tracked down to a broken wire, however I did replace both crankshaft sensors. Now I am receiving a p0386 code. does this mean I need to do a relearn procedure on the car, yes i did take the crankshaft out and inspected the bearings. 4.6 northstar engine
