hi there, the warm starting sounds like weeping injectors.
the keep leaking fuel after the cars stopped and flood the engine, there are posts on here showing how to check injectors are good.

hi mate,, cheers for tht. so jus replace the seals thn,, dont think they are tht expensive,, r they ??

no more likely the injector nozzle leeking, they can get little bits of debris in the injector which can stop the nozzle closing, used to be able to ultrasonicly clean them, but think that died a death when injector prices dropped. best to check the spray pattern (again explained on here somwhere) and if there knackered fit some more, 4 new injectors will set u back around a ton.

I've got the same syptoms on my 1600.. recently done prowlers injector test any they all leak a little  :cry: causing the bad warm starting

low idle on start up could be the aux. air valve on the back of the inlet manifold, not tested mine yet but when you start the car, squeeze the pipe coming out of the valve and the revs should drop and then pick back up when you let the pipe go (if it's working correctly)

easy,, checked air valve on the back of the inlet manifold and revs dropped as they should,, and my injectors are weepin jus like yours,,
