Does it idle smoothly for the 5 seconds and then shut down or are we talking about a really rough idle that the engine can't keep running with.

If you know very little about cars then it may be best to get it checked by a dealership.

Hi I am no expert not by a long shot but could this be due to an injector or fuel pump issue?
May be using the fuel that is still in the line then dying when that runs out, or could be a sticking injector where as when you give it some the sticky injector gets past the problem point allowing the fuel through but then removing your foot and the injector sticks again shutting fuel supply?

Is there a possibility of a bad batch of fuel eg water in the fuel or the likes?

Fuel delivery issues generally coincide with roughness, but it shouldn't be discounted totally.

These car are renowned for vacuum leaks on the inlet manifold at number 1 and number 6 cylinders where the inlet manifold meets the head at the manifold runner's lowest point. The retaining nuts come loose and the bottom third of manifold gasket burns out so it stalls at idle. The leak is small and will usually change as the manifold heats up and the gap size changes. It is very difficult to find these leaks with the traditional methods of spraying oil, water, starting fluid, benzene gas etc around the manifold as it's at the lowest point of the runner (so anything you spray has to defeat gravity) and the leak is very small (so the ECU adjusts the mixture almost instantly and no change in engine speed as a result of the sprayed substance being sucked into the manifold will be noticed). The best way to check for and find these leaks is to get a metre or so of soft rubber or nylon windscreen washer sized hose and stick one end in your ear while moving the other end around the inlet manifold (especially underneath the runners at number one and six) while idling the engine and listening for the sound of an air leak. Someone may have assist by holding the accelerator very slightly down so it doesn't stall and you need to do this with both a hot and cold engine. You could also use a mechanic's stethoscope with the metal rod part removed so you have just the open tubes to listen through.

The inlet vacuum leak is the most likely cause but if you can't detect a leak some other possibilities include a blocked air filter (but I assume the car has been regularly serviced and hasn't ben used in excessively dusty or dirty conditions - no red dirt outback Christmas road trip) or a sticking throttle body butterfly valve (take of the air inlet tube from the throttle body and spray liberally with throttle body spray cleaner).
