Thanks for the reply, ive had the inlet manifold off and cleaned out best I can and also cleaned the egr. Also ive performed the bg induction clean on the inlet. Yes the car runs perfect with the swirl flaps disconnected. When I re-connect them fault code 3FFO is set after holding the revs at about 2250 rpm and the engine is very lumpy. Open the swirl flaps manually and the car is fine.
Regards Jamie.
