It is literally a ten minute job. I kept throwing a CEL which stated a random misfire in cylinder #1. The dealership replaced the fuel injector and it hasn't come back on since. All you have to do is take off your plastic engine cover and remove the fuel rail. Unplug the injector and pull it out. The injector seals itself by compressing an o-ring into the housing and the fuel rail holds the injectors in place.
