My F5 starts and idles perfect, the powervalve cervo does its check when i start it the valves have just been cleaned and open and close smooth but from the second i start it the check engine light flickers on and off continuously... Anyone know what it could be, my thinking is a sensor but i dunno which one i dont even know what sensors it has

Call the dealer. They can give you the code if they are not A-holes.
