Engine management

I;ve got a focus tddi endura -year 2000,got smoke coming from
exhaust(grey) runs a bit rough and theres a kinda knocking seemingly
coming from the top left hand side of the engine,like a valve not
returning properly,ive removed and stripped down the head,decoked and
cleaned it all up new valve seals the lot,but the problems still there
:(

my engine management light comes on when i start the car but goes off
straight away,surely this light should come on and stay on if theres a
fault?? any ideas how this management system works,has a fault occured
in the sensors or summat????

Either you have an EGR fault (most likely) or a AFM problem.

That MIL behaviour is normal, and as far as the ecu is concerned there is no
fault.
