2011 Jeep Wrangler Rubicon JKU EGR replacement.

Replaced my EGR valve along with my purge valve and my purger canister.
I had been getting a P0406: EXHAUST GAS RECIRCULATION SENSOR A CIRCUIT HIGH fault code for a few years. It would clear when I put in a new PCV valve. I have no idea why. I am not a mechanic. I never got the stuck open or stuck close codes. I'm 225k miles and 7500 engine hours. I finally had the time to replace it. Around this time, I also started getting a consistent cylinder 5 misfire. All signs point towards the cylinder getting too hot. From what I learned through other videos, is that a well functioning exhaust recirculation system helps lower combustion temperatures, so by adding that information together, I went ahead and replaced my purge valve and purge canister. My jeep had been having trouble accelerating right when I would tell it to. It would kind of lag and then pick up. After replacing these components and cleaning my throttle body, the idle has smoothed back out and she accelerated when I tell her too.
