1.4 had a breather pipe under plastic manifold that rotted and sucked air and runs rough.Ht leads go faulty also.
run diagnostics for faults?

no codes or engine management light on, yeah 1.6 has the breather pipe behind manifold with a pcv valve on it I thought about that one , bit of a pain in the arse stripping all that off for a breather
