how to change injectors?
I learnt that my injectors on my car are not the greatest, they are giving a steady stream. My car revs by itself and sometimes at idle, it just dies. Is this due to the injectors?
i would like to change them, is there a guide or any steps i should follow?

well, It can't hurt getting your injectors professionaly cleaned.
To get them out you need to remove the upper intake manifold. the primaries are right on the block and the secondaries go into the UIM. To get at them you need to remove the fuel rails. Which I believe are held on by 12mm bolts(ithink all the manifold bolts are 12mm).
Remeber to replace the little rubber O rings when replacing the incectors cuz no matter how good they look, they will leak. AS for the secondaries don't forget to put back in the atomizers or at least the base of them as they are used in seating the injectors properly. Leaks if you don't
Hope this helps. After you've replaced them and got everyhting back together, make sure the idle is adjusted correctly and adjust the tps. Make sure plugs work good and the timing is correct. That should stop the problems.
