Hi everyone, I've stumbled onto this forum while searching for a troubleshoot to an issue I've been having. Seems like a great community so I will definitely be staying here. Anyways, I've been having a rough go with my 2012 Liberty over the past month. I've been receiving several error codes saying that my 3rd cylinder is misfiring.. I've been noticing that my Jeep stutters while on the highway and the acceleration is abysmal for a short time after I notice the stuttering. I've noticed that on the fuel rail the right side is capped at the end and on the left it is completely open at the end. The end of the rail appears to have dark colored ring to is as if there was possibly a cap previously? Just wondering if this could be the issue for the difficulties I'm noticing on the highway or not. Thanks in advance for any help!
