ok so since the time i installed 2000k intake manifold my focus start acting wierd....i mean like idels under 800rpm a bit and sometime makes me think its gonna die on me...but i guess i have to play with my TB a little bit

but my main problem is....it happed 2 days ago at first but then today i really started to pay attention to it

if im driving faster then 120-130km/h and then drop it from the gear to neutral,my car shuts off....i mean engine engine shuts off, power streering shuts off and im just rolling in the car there....like wtf?.....while im rolling there i can still turn it on but this is like so not good.....must be something with my ECU

oh and 3 days ago or so i had engine check come on and OBD2 read it as 1406 which is this rubber tube that connects to intake manifold
i ordered that tube from Ford and just have to pick it up

but any ideas on why my car shuts off like that?

i'll try to take a video clip
thanks
