Running rough P1316 and P1274 codes

On the way home from Montana last week my engine started running very poorly as we were driving on the highway and the service engine light popped on. I was thinking it was the UVC harness connection and pulled the valve cover on the drivers side. It looked a like it might have had a small gap so I was able to find the Ford retainers locally and installed them. Put it all back together, fired it up, no change. Checked the passenger side, tight harness. Started it again, no change. Stuck Auto Enginuity on it and a P1316 code came up. Ran a buzz test and the #4 injector was very quiet. The test result said P1274 - #4 cylinder high to low open. What I did not do was look at the terminals to see if any were burned. Other than that, am I looking at an injector problem or hopefully, still a harness issue?

Thanks, Mark
