2002 Escape Rough Idle

This is a video of my 02 Ford Escape. It has 143k miles on it. Was running just fine until around 2 days ago. Check engine light turned on and it idles pretty rough. There is a hose in the back that kinks because of the vacuum that i put a clamp on around 4 days ago. Car ran fine with the modification. But now, 2 days after the "half Fix" it starts acting up. Autozone said I had a Misfire on Cylinder 1 code 301. The day before i had this code plus another that said the engine was running to rich, aka too much fuel Any help would be greatly appreciated!!
