Vauxhall Corsa 1.0 Running problems

Engine is a 1.0 3cylinder in a 98 corsa. The following problems seem to have appeared over the last month and i think they are getting worse. Apart from the problems below the car pulls and drives fine and economy is pretty good to.

The car struggles to start especially when hot, often it sounds like it hasnt started so i stop turning it over then after a few seconds it will slowly kick into life.

It pinks quite bad if you suddenly press the accelerator to the floor.

When turning the ignition off it will run on for 2 or 3 seconds.

Any idea's what could be wrong.

Thanks

Anywhere in particular they fail on this model?

Thanks for you help.

I was going by your symptoms, rather than a common failure on the model. get a tin of spray carb. cleaner, with the engine idling spray around manifold gaskets, hoses etc. any change in running shows a likely air leak spot. I have found that model to be quite hard on spark plugs, so a new set might be a good idea, unless very recent.
