Message bad injector but could also be a bad coil or any number of things.

First thing I would do is find the source of the fuel leak as zellamay said as this is very dangerous. Second, I would pull each coil connector individually to see if the cause of your rough idle is due to any particular cylinder not firing.

If you isolate a particular cylinder that is not firing, swap the coil with one next to it and see if the missing cylinder moves with the coil. If the same cylinder is misfiring, you likely have an injector problem.

later,

eric
