Is this the reason my cylinder is misfiring?

If you look at that picture, the injector to the right is not wet, and there is a similar "stain" to the right of that second injector(possibly more than one leak?)....
Mike, I am not sure how spraying water will affect this? That rail is under pressure, not a vacuum........
If you smell gas, it'* kind of a no brainer, that you pull the fuel rail(very easy, just relieve pressure first at schraeder), and replace BOTH O-rings on each injector....have never seen an injector, crack and leak......but nothing surprises me anymore......
One of the things you can try, is wash down the suspect areas with Brake Klean, and then blow dry/clear the area of debris......cycle the key just to on(on for 5 seconds, off for 10) several times, to build up max pressure......now remove the retainers from the fuel rail.......now slowly grab the rail, and move it side to side(don't lift upward), and look for fuel possibly leaking from an O-ring....

Sounds like a bad o-ring. And it could have a effect on MPG.

Less fuel from injector could mean misfire up a hill & potentially be not firing the cylinder,
One less cylinder up hill means less rpm and bogging out..ahh putt putt mode.
