check for a very wet spark plug, you may have a leaking injector, but also check that you have good spark at all plugs and the plug gaps are not excessive, start here.

no, normally if you have a leaking injector it is the internal pintal that weeps they need to be flow tested on a bench tester to see how well they are working.
