That code, I would say about 85% of the time means you have a bad injector #3. The way to test to be sure is remove the valve cover and use a ohm meter and check the resistance of the injectors, the spec is more than 0 ohms and lest than 1 ohm, you will likely find that #3 injector is out of spec, if it is .9 ohm or higher, I recommend replacing that injector. This should fix the problem.....
