its like my car has no omph, ok i changed the spark plugs to its inst stalling. i think it may be ithe injector as it wants to move, when i put my foot down, sometimes it does. would putting injector cleaner from gargage help with this. i thinks its the red liquid you put in the petrol tank, any one help please..........

whoa, hold on a bit, its sounding more like some of the common faults of astras/ecotec engines here.

What engine is this?

Does it stall sometimes approaching a stop/giveway sign?

are you getting a spark across all 4 plugs?

My next diagnostic would be a carb cleaner

it was stalling , yes have changed the spark plugs, still feels a bit sluggish, then sometimes it goes, bit jumpy, still gonna get the injection cleaner and try that, any ideas, its a 1.4i

Sounds like you haven't put the HT leads back on the spark plugs properly.
Try pulling them all off and placing them back on again.
Also make sure they are in the correct order.
