P0307 is a misfire cylinder 7 code. Could be a bad coil, plug wire (If applicable) or bad injector. When engine is warm, use a meter to test across the injector and compare it to one next to it. This should tell you if the injector is shorting internally. Also you could check for spark using a spark tester.
