e16se misfire

[Andy]

misfire from e16se low down rev range.
when revved up sometimes the revs take longer than normal to drop.
just had a brand new head fitted for an unrelated matter.
it did it with the previous head also.
any ideas or advice is always appreciated.
any simple ways of testing ?

had this with a few cars now and ive found the seal on the servo pipe is perished but worth checking all the little vac pipes and checking the seal between the throttle body and manifold

aye.time to get handy with the double t spray lol

[Andy]

just sprayed all over checking everywhere,got to the injectors and it picks up.3 out of 4 make a difference when sprayed.
New seals required it seems
