i just got a b18b put in my civic and its odb-1... im having a problem with it idling up and down and kinda hard to keep running when cold.. Could the ICt sensor cause this??? ive just got the car back but my tech told me to take it back if it keeps doing it.. also could a clogged fuel filter do it??? It has a misfier to it but it doesnt set any check engine lights..not sure think ill mess around with it just seeing if i could get some suggestions.. thanx.
